Lindsay Lohan Plays The 'Passive Wife' in Relationship With Samantha Ronson

Lindsay Lohan is said to play the "passive wife" in her relationship with Samantha Ronson.

The 'Mean Girls' actress -- who is rumored to be dating openly gay DJ Samantha -- reportedly adopts a submissive role in their alleged relationship.

A source tells American magazine Star, "Lindsay and Samantha are totally playing house and loving every minute of it. And, yes, they share a bed!

"They both play certain roles. Lindsay is the passive one, the wife. It works for them!"

According to the publication, the young couple also shop for sex toys together and have made a "bizarre" pact to stay thin.

Lindsay, 22, and 30-year-old Samantha -- the sister of music producer Mark Ronson -- who first sparked rumors they were romantically involved last year, are rarely seen without each other.

The pair were photographed holding hands and laughing on the set of Lindsay's new movie 'Labor Pains', and were seen sharing an intimate hug and kissing during one of P. Diddy's infamous boat parties at the Cannes Film Festival in France in May.
