Lindsay Lohan and Samantha Ronson to marry?

Lindsay Lohan has announced she wants to marry Samantha Ronson.

The 'Mean Girls' star was seen sporting a ring at the Dolce and Gabanna party at the Cannes Film Festival, in France, and reportedly told her former lover, British model Calum Best, the pair are engaged.

Lohan, 21, and 30-year-old DJ Ronson - sister of music producer Mark Ronson - were also spotted at one of P. Diddy's infamous boat parties kissing passionately and draped over each other.

According to Britain's Daily Star newspaper, the 'Georgia Rule' star has apparently told friends she wants to have a partnership ceremony with Ronson at Dolly Parton's Dollywood theme park in July.

She is also referring to herself as Lindsay Ronson.

Rumours Lohan and Ronson are more than just friends have been circulating for months. Previously leaked emails from Lohan to Ronson said: "Babe, if I don't have you in my life then I should just go die. I want to marry you."

Reports also suggest that since returning from the world famous film festival, Lohan has moved into Ronson's Los Angeles home.
