Rihanna fainted on stage during her concert today at the Acer Arena in Sydney, Australia.

She was performing her song “Umbrella”, which was the grand finale of her concert. She had just come down from flying around on a harness. Her boo Chris Brown joined her on stage for the final performance of the evening. She was observed bending over and signaling that she wasn’t feeling well.

Poor thing then ran off stage, where paramedics went to administer medical aid to her. Chris, ever the pro, wrapped up singing the song and then rushed backstage to be by her side.

The concert ended without any mention of what exactly happened. Watch the video footage below! Let’s hope that Rihanna is stable now and on the road to a speedy recovery. Get well soon, RiRi!!!

UPDATE: “It was very hot at the venue, so after Rihanna’s set was over, she went off stage to sit down, catch her breath and have some water,” her rep tells E!. “She is perfectly healthy and will be at her show tomorrow.”

Rapper Mos Def is being hunted by the Las Vegas police department over his alleged attacking of a fashion event photographer this past August.

A warrant has been issued for Def — real name Dante Terrell Smith. He currently is facing charges of felony robbery and malicious destruction of private property.

Volker Corell who is the official photographer for the Men’s Apparel and Garment Industry Convention (MAGIC) in Las Vegas has claimed Def did the freak on him as he was taking pictures of attendees at the event until Mos allegedly yanked the camera off his neck, bashed it around on the ground and then left in a snit with the trashed equipment.

The photographer says his hand was cut during the scuffle.

Def’s hate on for the paparazzi is well known, but Corell was a photographer who was hired for the event and what’s ironic about it all? He says he didn’t even know who Mos was until after the alleged attack!

Ashlee Simpson and Pete Wentz’s baby will be arriving soon, and they are happily setting up the nursery making sure they have all the necessary essentials. A friend told Life & Style:

“She’s having a last-minute baby shower tomorrow, The location is top secret. They’ll send out an e-mail to all invited guests early Saturday morning. She was eyeing the Bel-Air Hotel in LA — but no one will know exactly until tomorrow morning. This could be the last chance for everyone to see Ashlee before she becomes a mom.”

Rather interesting… if it’s supposed to be top secret, why tell a magazine that it’s on and what day? Why not ‘leak the tidbit of news’ after the shower is over? Makes me wonder about these so called ‘friends, insiders, unnamed sources’ telling secrets for money … !

Excited daddy to be, Pete recently told Ryan Seacrest:

“I am on call permanently right now. She’s at the very end, and it could happen at any point.”

Old school Aussie rockers AC/DC are now the second biggest sales debut artists of the year, with 784,000 copies of their newest release Black Ice selling this past week.

This week AC/DC’s “Black Ice” managed to push the soundtrack of High School Musical 3 from the top slot as they only sold 297,000 copies of the soundtrack. The film grossed $42 million in its opening weekend, and the disc, like most soundtracks, will more than likely see a sales spike the week that the soundtrack is available simultaneous with the film being in theaters.

What is interesting to note is that AC/DC won’t release their stuff to iTunes or Napster, they only released it at Wal-Mart, Sam’s Club, and AC/DC’s website so people can’t download it… yet the results are in, and look at how many CD’s they sold with such a limited release.

Lil Wayne’s Tha Carter III currently holds 2008’s Number 1 spot for the year with 1 million copies selling in a week.

Ahh, the life of the rich and famous. Here is MJ getting out of a limo at the home of his long time friend Elizabeth Taylor. Nice to see he dressed for the occasion, he’s in his jammies.

His new compilation album King Of Pop has re-entered the top ten of the album chart just this past week. The dramatic jump happened after contestants on Saturday night’s TV talent show X Factor were asked to sing some of his hits. The album’s release was timed in conjunction with his 50th birthday.

He recently just moved into a mansion in Las Vegas with his three children and the home is located just metres from a school which takes pupils aged four to 13.

This has upset parents of the 600 children at the school and they have complained about his choice of residence.

One parent told The Sun newspaper: “Some parents say they don’t want their children near Jacko.

“They say he can see the kids getting on the school bus from his house.”

According to the newspaper, Jackson and his kids are being put up by casino owner Steve Wynn who is trying to persuade the shy star to appear in a comeback show.

Area residents say that the superstar has not been to the school and keeps a low profile, surrounded by a team of bodyguards, but since his arrival, fans have been congregating outside the gates of his Spanish-style villa.

A school spokesman refused to comment.

A Long Island judge has granted 50 Cent regular access visits to see his 11-year-old son, Marquise Jackson. The custody has been arranged and 50 is now allowed one weekend a month, one month summer vacation, and half of the time their son is off school during Christmas and Spring breaks

The legal battle between 50 and his ex-girlfriend, Shaniqua Tompkins is ongoing. She was granted an order of protection against him. Shaniqua stated that she felt 50 Cent may have been responsible for a fire which gutted his $2.5 million dollar long island home while she and Marquise were sleeping inside.

50 Cent strongly denied her claims and responded by filing a $20 million dollar defamation lawsuit.

Because of the Order Of Protection that Shaniqua secured against the rapper she had to drop their son off at a police precinct in Queens on visiting weekends where the boy was picked up by 50 Cent or his driver. Not sure if that arrangement is still in effect.

The cause of the “suspicious” fire at 50’s Long Island Mansion is still undetermined.

Lindsay Lohan is being sued by three guys in an SUV she drove during a car chase that resulted in her second DUI arrest last year. The past really can come back to haunt a person! Her legal fees will be outrageous to defend herself. She better get some work, make more money, ’cause she’s going to pay pay pay.

The actress was “angry and aggressive” and the guys “felt surprise, shock, fear and panic at Lohan’s surprising and sudden act” of allegedly commandeering a car in which they happened to be sitting to chase her personal assistant through the streets of Santa Monica, according to the lawsuit.

Ronnie Blake, Jakon Sutter and Dante Nigro who are the plaintiffs – are seeking unspecified damages in the case, filed in Superior Court in Santa Monica.

Though no one was physically hurt, their lawsuit describes a wild, traumatic ride with Lindsay supposedly upset and intoxicated as she went after the other car following a party.

“Dante and Jakon continued to implore Lohan to slow down, stating specifically that she was endangering all of their lives and that they could be killed,” the lawsuit says. “Lohan refused to slow or stop, but instead responded with abusive cursing and vulgar language, including a statement that she did not care about the risk of death.”

The lawsuit adds: “She also stated that because she was a celebrity she could do whatever she wants.”

Lohan’s attorney, Ed McPherson, tells TMZ.com the lawsuit is “absurd.”

“These guys had the night of their lives, playing with the radio and leaving the vehicle at one point and getting back in,” he says.

After her arrest Lindsay reached a plea deal in the case and spent 84 minutes in jail for DUI.

She also was sued by the passenger in the car she was chasing.

Lil Wayne is shown here holding up his Lyricist of the Year award during the BET Hip Hop Awards ‘08, this past Saturday in Atlanta. Ever the professional, he made sure he left in plenty of time to make the hearing for his weapons case in New York today.

A cop testified last month she boarded Lil Wayne’s bus after a concert because she smelled marijuana. She said that while on the bus she saw him try to hide a gun.

His defense attorney Stacey Richman wants the charges dismissed. She says police falsely claimed they smelled marijuana so they could illegally board the bus.

TMZ who had a staff member present in the court room reported an amusing snippet of detail:

” Our guy in the courtroom says everyone got an impromptu Marijuana 101 lesson in the process.

Not everyone was so stoked - our spy says Wayne sat, head in hands, watching his lawyer battle to get the case skunked.”

Nelly Furtado confirmed during an interview with Entertainment Tonight on Friday that she secretly married sound engineer Demacio “Demo” Castello this past summer. They had worked together on her 2006 album “Loose” which included her hits “Promiscuous” and “Maneater.”

The couple had been engaged since last year.

Nelly who is 29 years old has a four-year-old daughter from a previous relationship that ended in 2005.

She said:

“We got married July 19th, “I love it.”

She went on to say: “It’s a nice phase of my life. I just feel kind of free and relaxed and more in tune with trying not to be so stressed out,[I'm] trying to enjoy things a little more.”

She also added: “I’m happy … I’m excited about the future.”

Congrats to the happy couple.
