Lindsay Lohan 'Will Dump Samantha Ronson For a Man'

Lindsay Lohan will dump girlfriend Samantha Ronson as soon as she finds a suitable man, friends of the Mean Girls actress have said.

OK! magazine reports that when Lindsay and Samantha were at the Delano Hotel's Florida Room on August 5, Lohan cozied up to other men whenever Ronson left her side.

"Lindsay was laughing and giggling with these guys," an eyewitness tells the magazine.

"Lindsay is the aggressive one in the relationship," an insider says. "Sam tries to focus on Lindsay, but it's never enough."

Another friend adds that cracks are already appearing in the couple's relationship, and that "Lindsay has to be the center of attention, or she'll flirt with other guys to make Sam jealous."

But, back in Los Angeles as they partied for Sam's birthday on August 6, the pair were "hand in hand and very affectionate" at Crown Bar.

"The situation is between them," says Lindsay's dad, Michael Lohan. "God tells us to love each other, and love doesn't discriminate."

But Lindsay's friend says, "She'll be with the next guy who catches her eye — she can't help it!"
