Will Lohan wear white to her wedding?

Word is Lindsay's boyfriend Harry Morton was checking out engagement rings for the Lohan at Cartier in Beverly Hills. His "aides have confirmed he did in fact buy something special there."

Morton's rep says, "I can confirm that Harry was shopping in Cartier, but what he purchased I cannot confirm. If it was in fact a gift then that's between him and whomever the gift is for." Dog tags?

Update: Lohan's mom tells Star that Lindsay is definitely not engaged
