"Friends" star David Schwimmer is reportedly romancing "Sex And The City" actress Kim Cattrall.

The pair, currently staying in London while starring in West End plays, have been seen on a string of dates together and even spotted kissing, reports Internet portal Femalefirst.

However, a representative for David, 38, insists he isn't dating Kim, 48. "I don't think he knows Kim Cattrall," he said.

David was said to have been devastated when girlfriend Gina Lee ended their relationship last year. Her friends claim she broke up with the actor because she didn't have anything in common with him and was romancing him just to get over her former finacé Kenyon Phillips.

Kim is said to have recently ended her relationship with a Canadian chef, 21 years her junior.
