Lohan gets in Cat Fight!

According to Page Six "X-MEN: The Last Stand" director Brett Ratner never bothered to tell his "friend" Lindsay Lohan that he had a girlfriend - resulting in a loud, messy fight between the young star and Romanian IMG model Alina Puscau at Ratner's home last week. Late Monday night, Lohan - who has become close friends with the director in the past month - and a pal decided to pop in on Ratner unannounced. "Brett wasn't returning any of her calls, so she decided to stop by and say hi," a source told Page Six.

"Brett never told Lindsay he had a girlfriend. She had no idea," the source said. "He is constantly e-mailing, texting and calling her. She just wanted to hang out. He had given her the code to his house and told her to come over anytime, so she went." But once at the house, Lohan was shocked when she found Ratner in bed with his girlfriend, Puscau. "Alina jumped out of bed and went ballistic," another source said. "They started screaming at each other and took the fight first into the living room and then out to the driveway while Brett hid in the bedroom.

"Lindsay said she could get Alina deported and left. What she doesn't know is that Alina and Brett are so serious, he gave her a big diamond promise ring last November which she wears on her right hand. She doesn't care that he may cheat. She's got the big diamond ring." The source added: "Brett is a 37-year-old man, and Lindsay is a 19-year-old girl. Enough! He needs to stop bothering her, it's embarrassing. Lindsay is happily dating [Keira Knightley's ex] Jamie Dornan - she just wanted to be friends with Brett." Lohan and Ratner patched things up enough for Lohan to return to the scene of the fight Tuesday night for a Victoria's Secret party he was hosting at his home. "Lindsay has a long relationship with Victoria's Secret," one source sniffed. "Of course she was going to support them." No word on whether Puscau attended the party as well, but Kate Bosworth, Matthew Perry, Owen Wilson, Chris Tucker, John Mayer and Lance Armstrong did. Lohan's rep said: "Lindsay is friends with Brett but has romantic interests elsewhere." Ratner's rep declined to comment.
