Lindsay Lohan must have thought there was something serious between her and Brett Ratner -- right up until the moment she found the director in bed with his girlfriend.
According to gossip rag PageSix,, Hohan and a friend reportedly stopped by Ratner's house 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, Romanian model Alina 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."
Hohan's mouthpiece later issued the usual statement of denial: "Lindsay is friends with Brett but has romantic interests elsewhere." Ratner's rep declined to comment.
