Lindsay’s last stand.

According to a report in Page Six of the New York Post, Lindsay Lohan continued her embarrassing pursuit of significantly-older director Brett Ratner last week, dragging a pal with her when she dropped by his home unannounced. But instead of finding him alone and pining for her company, she walked in on Brett and his, apparently unbeknownst to Lindsay, girlfriend, model Alina Puscau.

"Brett never told Lindsay he had a girlfriend. She had no idea," Page Six’s 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."

And in typical Mean Girl fashion, a war of words ensued shortly after Lindsay’s discovery.

"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."

Despite the drama, Lindsay and Brett put their performance skills to work the evening following the incident at a Victoria’s Secret party held at his home. Which really isn’t all that surprising—when has there ever been a time when you’ve heard of Lindsay turning down the opportunity to party?

"Lindsay has a long relationship with Victoria's Secret," the tabloid was told. "Of course she was going to support them." Which makes sense. After all, they’ve been supporting her for years.
