Lindsay Lohan's two friends allegedly robbed Hollywood Hills mansion: Report

Lindsay Lohan apparently keeps some shady company.

The "Mean Girls" star brought two men with her to an all-night house party at a high-class Hollywood Hills mansion on Sunday, and after it was over, the mansion's owner said the men robbed him, according to TMZ.com.

The gossip site reported that the owner invited Lohan, 26, and that she showed up with her brother, Cody, her assistant and the two men.

Lohan and her crew left around noon Monday, but before they could leave, the owner reportedly noticed that some expensive watches and sunglasses were missing.

He called the cops and told Lohan and Co. to stay until authorities arrived, a request they complied with, TMZ said. When police arrived, they questioned Lohan, but after they told her she was not a suspect, she and the gang bolted.

The man reportedly told the cops that he thinks Lohan's two unknown guests stole all of the gear, TMZ said. The case is under investigation.
