Lindsay Lohan pal and rumored lesbian lover Samantha Ronson has posted a widely circulated photo of the two of them kissing on her MySpace page.

The photo, which was taken at a party in May on Diddy's yacht in Cannes, is not posted as Ronson's profile picture, but appears in one of the 30-year-old's photo galleries.

Meanwhile, hip-hop DJ Ronson has bought a $22,000 Cartier diamond ring for the 22-year-old actress, a source told the U.K.'s Daily Mirror.

"Sam took Lindsay shopping to celebrate her 22nd birthday," the source said. "Although Lindsay is the major breadwinner, Sam has her own money and is very proud.

"It's not an engagement ring — simply a token of her commitment. Lindsay is thrilled and she and Sam are very content."
