Lindsay Lohan Becomes Possessive Of Samantha Ronson

Lindsay Lohan has become possessive of her friend Sam Ronson. The actress reportedly became jealous of the attention her DJ/musician friend bestowed on Ashley Olsen at a party in New York.

Lohan, 21, and Ronson, a known lesbian, were partying together at the Beatrice Inn in New York on Friday, when the "Mean Girl" actress lashes out at Olsen for getting close to Ronson.

A source tells DailyBlabber, "Ashley Olsen said hello to Sam at the Beatrice, and Lindsay screamed at her, 'Get your 15-year-old a** away from my girlfriend."

Lohan also became upset when on Saturday, Ronson ignored her as she was focused on her DJ work at the Hawaiian Tropic Zone.

The insider continues, "Samantha was really focused on her work and didn't leave the booth for anything."

Reports say that the actress even created recently a profile named "Lindsay Ronson" on a popular social networking site.
