Lindsay Lohan has hinted she wants to wed her gal friend DJ Samantha Ronson. The 21-year-old star was seen wearing a big ring at the Dolce and Gabanna party at the Cannes Film Festival in France, and allegedly told her former flame, British model Calum Best, the pair are engaged. The two ladies were also spotted showing her affection at one of P. Diddy’s boat parties. "Lindsay and Sam may insist they're just good friends but there's no denying their chemistry. They were holding hands quite openly and Sam was stroking Lindsay's wrist really affectionately," Contactmusic quoted a source as telling. Other reports claim Lindsay has told friends she wants to have a partnership ceremony with Ronson at Dolly Parton’s theme park, Dollywood, in July.
