Lindsay Parties with Diddy and Cameron Before Getting Ugly

L.L. hits up Diddy's celeb-heavy party before getting to work on Ugly Betty the morning after

Lindsay Lohan may have been hard at work on the set of Ugly Betty Saturday, but not before hitting Diddy's exclusive party the night before. The hip-hopper, who received a star on the Walk of Fame earlier that day, threw an "intimate" bash for 250 friends—whom he personally invited.

The party was held at billionaire Ron Burkle's Beverly Hills estate, and although L.L. came to celebrate, she was on her best behavior. According to one partygoer who observed her that night, she wasn't drinking.

Also spotted at the swanky soiree: Cameron Diaz, who's partying in public for the first time since her father's sudden death. She did attend the premiere of What Happens in Vegas on Thursday, but opted out of going to the film's after-party.

Apparently, when Diddy throws a party, no one can resist dropping by.
