Now that Lindsay Lohan is losing her shit in the wake of her split from Samantha Ronson, the British DJ’s mother and sister are hard at work to try and get a restraining order placed on the redheaded actress.

The two have inquired with the Beverly Hills police and according to Beverly Hills Sgt. Nutali, “They were directed to the court to get a restraining order.”

On Friday, Lindsay was barred by security from entering Charlotte Ronson‘s party, where her sister Samantha was trying to avoid Lohan. Following the couple’s spat that night, the locks at Sam’s home were changed on Saturday.

Unfortunately for Samantha, this isn’t all that effective since Lindsay’s skinny enough to slide right through the keyhole.
