After lunching with her sister, Mischa spent the afternoon shopping...and shopping...and shopping! She hit up three vintage stores before getting into her car – which was ticketed while Mischa was so busy droppin some cash – and headed over to...you guessed it, another store!Pulling into the Marc by Marc Jacobs, parking lot Mischa scraped her bumber on the gate and it fell in the parking lot! This was only a few weeks after she got into a fender-bender with Nicole’s car! She's either got the worst luck with cars, or she's the worst driver in the world!

Best pals Nicole and Mischa intended on spending a leisurely Sunday together...a little lunch, a little tanning...but things quickly took a turn for the chaotic when Mischa, driving Nicole's car after dropping her off at the tanning salon, took her foot off the brake for one minute and hit the car in front of her! The other car seemed to sustain very minor damage, but Nicole’s front license plate fell off! Wanting to get out of the street, Mischa pulled into a gas station, and seemed surprised that the other car followed, to exchange information. No one was hurt, but Mischa gave the couple her phone number and insurance information before calling Nicole to let her know what happened. Mischa then went and picked Nicole back up at the tanning salon. You'll never guess what they did after to calm Mischa's nerves! That video coming soon...

X17 has just discovered that Britney visited a surgeon a few days ago to discuss another operation on her busted knee. Considering that her last knee injury brought an end to her tour (and enabled her to spend more time with then-boyfriend Kevin Federline), let's hope it's not necessary - and if it is, that she'll pick a more suitable back-up dancer to help "nurse" her back to health!

Our beloved Lindsay, being all patriotic with her USA shirt, doesn't seem to be on top of her game recently. She's being escorted around town by her mom and going to AA to clear up some 'issues.'

Is Lindsay down in the dumps about all this? Well, we'll have video coming soon to show you how things went for her yesterday as she went to an AA meeting. And you'll never guess where she went after that ...

Angelina Jolie was reportedly involved in an accident earlier today in Pune, India, when the car squiring her back and forth between her five-star hotel and the set of A Mighty Heart allegedly struck an Indian couple riding a motorcycle. We haven't heard any gruesome reports from the scene yet (although we know for certain that Angelina was fine) and the couple hasn't filed a police report yet, but the scene painted by these pictures looks pretty crazy - let's hope Angelina didn't leave her Allstate card at home!

We don't usually think of Tom Cruise as being the cheating type because we don't usually think of Tom Cruise as being attracted to women, but when a hot Malibu soccer mom does her best to reel him in at their kids' game yesterday and while Katie was still off frolicking in France with Posh, it looks like Tom's at least hooked ...

This is an heiress, her name is Paris.
To In 'n Out she goes to get
Some food to eat in her private jet.

I guess the good thing about flying private is that instead of eating crappy airline food you can bring your own crappy food to eat and second, you can wear the worst clothes in your closet and no one but the pilot will see you (unless you're Paris and your every move is caught on camera) ...

Good thing that water pipe broke in Area last night - with all the celebrity firepower packing the club, everyone probably could have used a nice cool-down!
The club was set to be the scene for Nicky Hilton's 23rd birthday party, so unsurprisingly we caught Paris, Nicky, Brandon Davis, Elliot Mintz, Kim Kardashian, and Caroline D'Amore making an appearance - but we certainly weren't ready to see Lindsay Lohan pull up to the club!
And while we haven't heard any reports of punches being thrown between any of the parties involved, this video sure makes us think something happened inside - when the aforementioned pipe breaks, driving all the patrons outside, Team Firecrotch climb into Paris' SUV and leave Lindsay all by herself in a club full of dirty water!

Lindsay Lohan might have been raising a high holy stink over her broken wrist over the weekend, but when we ran into her this afternoon, she was going all out to make sure we'd never see it!
Lohan, on her way to a Santa Monica restaurant for an Italian lunch with some friends, declined to comment on the lawsuit she'd been threatening against Milk Studios (site of the break) - but the way she kept trying to hide her cast with her bag or a scarf have us wondering what all the secrecy's about. Who knows - maybe she just couldn't get a cast to match her hair!

Our X17 photog Josh, who was smashed into by Ms. CrazyPorsche (not Ellen, the woman you'll see at the end of the video), will be interviewed tonight on Extra -- check it out!

Here's exclusive video of just moments after Ellen's crash on Friday and here's how it went down ... Guy in a Honda, Ellen in her Porsche with her Portia, our photographer and his girlfriend, all stopped at the red light at Laurel and Sunset ... moments later, another woman (check her out at the end of the video) slams her Porsche into our guy (check out the trunk of his car) and his car pushes forward into Ellen's.
The producers of Ellen's show have already contacted our photographer and asked him to appear on the show to give his account of the accident ... we'll keep updated.
