Either Lindsay Lohan is on a mission to make rumoured girlfriend Samantha Ronson jealous, or she's getting her party-streak back!

New reports claim the actress has been flirting with men and meeting up with her exes - much to Sam's disgust.

The Mean Girls star was seen cuddling up to other men when rumoured partner DJ Sam turned her back.

"Lindsay was laughing and giggling with these guys,” an eyewitness explains.

"Sam tries to focus on Lindsay, but it's never enough."

"Lindsay is the aggressive one in the relationship," an insider admits.

Is Sam being played for a fool and is their relationship on the rocks, or is Lindsay just having a laugh?
