After Samantha Ronson split with Lindsay Lohan
over the weekend, the deejay's family inquired about obtaining a restraining order against an unidentified person on Monday, PEOPLE has confirmed.
"On Monday, April 6, 2009, at approximately 5 p.m., members of Samantha Ronson's family came to the Beverly Hills Police Department," a police spokesperson says. "They were given information for the process of obtaining a restraining order which will be administered at the Santa Monica Superior Courthouse."
It's not clear whom the restraining order would be against. But on Friday, Ronson and her family blocked Lohan from the "I Heart Ronson" bash at Bar Marmont, an event celebrating Charlotte Ronson's clothing line. "Lindsay was banned from the event and was trying to enter from all ends," a source tells PEOPLE. "Sam did not want her there."
Since their breakup, Ronson, 31, and Lohan, 22, have both sought support
from family. Sources tell PEOPLE that Ronson's family hopes this time, the break will be for good, while those close to Lohan say the actress needed some time away from her girlfriend to focus on herself and her business ventures.
Still, another source says that Ronson and Lohan "are totally communicating," though they have not been spotted together.
While her family was asking about the restraining order, Ronson herself was in Las Vegas on Monday where she deejayed at Prive as part of her regular monthly gig. "She seemed really happy last night, a lot happier than she did the last time she played," a source at the club says, noting that Lohan surprised her then-girlfriend during her deejay set in March.
