Lindsay Lohan knocks father while he tries to get her back in rehab

Lindsay Lohan made an appearance on Thursday night at Kitson Men in West Hollywood for the Jermaine Dupree and Pascal Mouawad's Nu Pop Movement launch party.  Not only was she looking like a hot mess, but she also took a few low blows at her father.

As the paparazzi surrounded Lindsay, she suggested that the photographers should be swarming her father, Michael Lohan.

"Why don't you go find my dad, he's the one who wants to be in the pictures," Lindsay joked.

Michael says he is trying to release a series of recorded messages to try and get Lindsay to check into rehab.  He says the recorded calls prove that his daughter was dating Heath Ledger at the time of his death.

In a recent interview, her mother says Lindsay drinks, takes Adderoll and cuts herself.  Dina Lohan even suggests that Lindsay might kill herself the same way that Heath Ledger did.
