Lindsay Lohan is facing more drama with rumored ex-girlfriend Samantha Ronson -- the DJ has locked Lindz out for good!
Friday night, the "Mean Girl" was banned from Charlotte Ronson's party -- and Saturday night, Lindsay got the love lockout at Sam's L.A. house! According to X17online.com, a locksmith was called to Ronson's home to have the locks changed -- so Lindsay couldn't get in!
A source tells the agency that Ronson's family's feelings about Lohan may have sparked the alleged split. "I'm sure Lindsay and Sam are over. Sam's family wants her to get away from Lindsay -- they think she's completely nuts!"
