The police are at Lindsay Lohan's home right now, Breaking Celebrity News has confirmed, and a source says it's because her father Michael Lohan showed up unexpectedly, and she wants him off her property!

According to the source, Lindsay has been partying hard lately and her dad stopped by to stage a sort of intervention for his troubled daughter, but she called the cops on him.

"Lindsay doesn't want her dad anywhere near her right now," the source said.

"But Michael's always trying to put himself in the middle of whatever is going on in her life. He's been worried about her ever since the fight she had with Dina last week."

Lindsay also failed to show up for work on The Canyons movie set on Wednesday, causing more concern for her close family and friends.
