sketch 3 010709 Enjoying an evening out on the town, Kate Moss was spotted at the launch party for ‘Beth Ditto at Evans’ held at Sketch in London on Wednesday (July 1).

Joined by her man, Jamie Hince, the catwalk queen was clad in a sexy black ensemble as she flashed her undies for paparazzi while hopping in and out of her chauffeured ride.

In related news, rumor has it that Kate and her rock star boyfriend are engaged – as the supermodel was seen wearing an expensive looking diamond wedding band on her ring finger while in Paris, France.

“Kate and Jamie looked totally loved-up. Jamie took her to the trendy La Maison Du Caviar restaurant for a romantic lunch,” a source said.

Earlier in the year, Jamie made hints that he may engage soon, saying, “I want to marry Kate. She’s all I want. She’s all I need.”

When Kate’s friends saw the ring, she was very private. “People kept noticing the ring on her engagement finger but she didn’t say anything,” told a source.
