OMG!

Samantha Ronson had a DJ gig in Calgary last night, but she's back in LA with Lindsay, and X17online can report that there are currently FOUR cop cars parked outside of their Hollywood home!

Just five minutes after Sam got back from the airport, she got into a screaming catfight with Lindsay. One of the windows is broken, and we're being told it was the neighbors who called the cops. When the cops went to the door, they knocked nonstop for twenty minutes, but no one answered.

It appears as though the cops will try to serve Lindsay with the arrest warrant, but the girls aren't exactly being cooperative!

UPDATE:
The cops are no longer in front of Lindsay's house, but they are parked two blocks away. It's being reported that Lindsay is set to appear in court on Monday morning, and if she makes a public appearance before then, she could be arrested. Think she'll risk it?

More details, pictures and video coming - stay tuned!

We STILL can't believe this happened! The man in the picture above was attacked by Chris Brown's bodyguard at a gym in Hollywood yesterday afternoon. The man and his young son simply wanted a shot of the R&B singer, and as soon as they snapped a few candid photos of Chris, the bodyguard went crazy!

The man spoke with X17online exclusively and told us what went down:

"Chris was inside, and there were all these guys outside trying to get pictures. I was just working out at the gym with my son and we wanted to take a quick shot of Chris. I guess Chris' bodyguard assumed I was a paparazzo and he started chasing me out of the gymnasium and down the stairs. I tripped as the bodyguard was chasing me - he was really angry and charging at me - I honestly thought the guy was going to kill me!

Then the guy picked me up and started shaking me with incredible force. He tried to grab the camera from my pocket but I didn't let go. People around were yelling, "Leave him alone; leave him alone!", and after a few minutes, the bodyguard realized a lot of people were watching, so he stopped. Thankfully there were witnesses - otherwise, I don't know what would have happened!"

We think the worst part is how Chris handled the incident. After the attack, Chris and the man went to the gym's office to speak with personnel, at which point Chris said, "I've never seen a white boy run that fast." Minutes later, Chris left the scene of the crime, and he let his bodyguard clean up the mess.

Hmm, sound familiar?

Whitney Port hosted a party at Tao in Las Vegas last night, and even though we're not 100% on her outfit, her hair and makeup sure look lovely!

Party until 4:30am, of course!

After the Beverly Hills Police Department issued a $50,000 warrant for Lindsay Lohan's arrest yesterday, the starlet went to Chateau Marmont to get her party on, and she didn't get back to Sam's until 4:30am!

Calls to Lindsay's attorney and rep were not immediately returned, but sources tell X17online that Lindsay may not have to turn herself in - that this is likely an issue her legal team can sort out. Okay, so what's going on here?!

Stay tuned - we'll give you the latest details as soon as we get 'em!

Okay, it's not quite what you think. Nadya Suleman took her kids (well, half of them!) to Disneyland yesterday, and she posed for pictures all over the park. Is she still trying to convince us that she's a good mom?

Tara Reid and her buddy Dean went to Guy's last night, and while I'm not loving her dress, she looks pretty fab otherwise! Her skin is glowing, and she seems to be at a healthy weight, so good for her!

Now, can someone please cast her in a movie? That's a comeback I'd like to see!

Angelina Jolie must be freezing! Sure, she's bundled up in a long down parka, but those bare feet - eek! Someone get her a pair of Uggs, stat!

Maksim is totes the hottest guy on the show, and well, Denise is the hottest (and most famous) girl on the show, so we think this title is 100% accurate! We snapped Karina's man and the Bond babe out and about in Bev Hills yesterday afternoon, and we have to say, Denise is looking SUPER hot...don't you agree?
