A gaunt-looking Lindsay Lohan hit Jermaine Dupri and Pascal Mouawad's Nu Pop Movement launch party at Kitson Men's in West Hollywood Thursday.

With messy hair and a thinner-than-ever frame, the actress, 23, appeared disheveled as she spoke with reporters. Inside, she smoked, played with her Blackberry and scored "tons of swag," according to E! News. "When given a free watch, she joked about giving it to her estranged dad Michael," E! reports.

She is currently in a war of words with Michael, who has been releasing disturbing old taped phone calls in an attempt to get her to go to rehab.

In a conversation released this week between Michael and Lindsay's mother Dina, Dina says Lindsay cuts herself.

"It's bad, Michael. It's bad," Dina tells him.

Another recording revealed that Lindsay was dating Heath Ledger around the time of his 2008 death.

Dina is heard saying that when Lindsay "is drunk or takes an Adderall with it, she will do something like Heath Ledger did in a second without thinking."

Dina lashed out at Michael for releasing the calls.

Remember these nasty family feuds?

"The tapes were from a long time ago, and for a father to stoop this low is unforgivable," she told E! News. "My ex-husband has been in and out of jail for 10 years. My children and I gave him a chance to get to know them again, and he clearly blew that chance!"
