Look out Xtina -- there's a new diva in town, and he might be even nastier than you!

When Justin Bieber appeared on the Australian TV show Sunrise last month, the 16-year-old pop singer allegedly got testy with a stage manager when he attempted to show the singer where to go prior to his performance.

In a radio interview yesterday, Sunrise host David Koch said, “We had him on and he was a thoroughly nice bloke ... a really decent guy. But our floor manager was directing him to where he was about to perform and [Justin] turned around and said to him, 'Don’t ever f*cking touch me again'!"

Koch added that Bieber’s sound technician said the pop star is known for his foul mouth, but Justin defended himself on Twitter the other day. "Family time with my mom couldn't come at a better time....I was raised to respect others and not gossip...nor answer gossip with anger," he tweeted. "I know my friends family and fans know the person I am. Hearing adults spread lies and rumors is part of the job I guess."

Simon Monjack will be laid to rest today at Forest Lawn Memorial Park in the Hollywood Hills next to his wife, Brittany Murphy. Monjack, a screenwriter, was found dead in his home this past Sunday ... the very same house where his wife died six months ago. He also shared the home with Brittany's mom, Sharon.

On Tuesday, an autopsy was performed on Monjack, but the coroner's office says that it will be weeks before the actual cause of death is determined.

According to Monjack's rep, he suffered from a heart condition. The private service at Forest Lawn will take place at 3pm.

Lucky guys! Yesterday Paris and Nicky Hilton attended the USO Swinging Salute to our Troops Fleet Week kick off at the Union Square Ballroom in NYC, and it looks like the ladies had a great time posing with the boys. Think Miss P snagged herself a sexy sailor? She certainly looked like a vision in white, and Nicky looked just as hot in a simple black dress and a pair of heels we're dying to steal.

We can't even believe what we're looking at here! Rapper/actor over 50 Cent lost over 50 pounds for his upcoming movie Things Fall Apart, going from 214 pounds to 160 in just 9 weeks. 50 plays a football player diagnosed with cancer, and of the transformation he says, "I was starving." We can see that! But fear not, the rapper is back on tour and getting his appetite back, adding, "I'll be back in shape in no time!"

Just because she's banned from Trousdale and banned from drinking alcohol doesn't mean she can't hit the clubs and have a good time!

Last night Lindsay Lohan and some pals hit the Chateau Marmont, and later we caught the newly blonde starlet at Las Palmas, the new Wednesday hotspot. Lindsay appeared to be in a great mood, and we couldn't detect her SCRAM bracelet under those flared jeans, but we suspect she planned it that way.

It's good to see her smiling, but these lips look like they belong on Janice Dickinson!

Kim Kardashian turned up the glam in this black pants suit for the Armani Exchange and Elle Creative Director Joe Zee's "Disco Glam" night at the store on Robertson. She even matched the look with black nail polish and black accessories -- cute!

Sure, she may have had botox once or twice, but those curves are all natural!

David Beckham (aka the best dad ever) treated the boys to a little frozen yogurt after picking them up from school yesterday.

We're sure David was happy to be spending quality time with his sons, Brooklyn, Romeo and Cruz after spending a few days visiting the troops in Afghanistan, but is David over-indulging? After all, this is not the first time we've seen him showering his boys with love and fro-yo but as an athlete, shouldn't he be a little more concerned about what they put in their bodies?

Just because it's yogurt doesn't mean it's healthy!

Tonight's American Idol finale was filled with comedy, drama and most of all, a sendoff to the person who made the show for the last nine seasons: Simon Cowell.

The stoic Simon even got a little emotional during a tribute that included the return of Paula Abdul live on the Idol stage (as X17online first reported), a roast by comedians Dane Cook and Ricky Gervais, the first time all former Idols appeared together on the stage (except for David Cook?!?), and a standing ovation from the audience.

In fact, it dominated the two-hour finale of the show that's seen it's ratings tumble in recent years from the television juggernaut it once was, even overshadowing Christina Aguilera's first performance of a single off her new album since she announced she was cancelling the tour, Alanis Morrissette's duet with Crystal Bowersox, Janet Jackson with a fierce new haircut (and performance to match) and the return of BRET MICHAELS!

“The show goes forward, it will be different,” Simon said during a heartfelt speech in which he reiterated that America is the real head judge of Idol.

Phew, so much more went down that we almost forgot why we were here -- to crown the season 9 champ. (SPOILER ALERT: If you're on the west coast, read no further.)

And the next American Idol is ...

Lee DeWyze. Shocker.
