Kristin Davis has admitted that she dated one of her Sex and the City co-stars during the early days of the show.

The actress, who played Charlotte on the hit US series, is keeping tight-lipped about the identity of the actor in question.

"In the early days, before there was so much focus on us, I did go out with one of them but I'm not going to say which one," The Mirror quotes Davis as saying.

"It got to be the kind of thing where there was so much attention and gossip and weirdness that I felt like, 'Oh, I don't want to mix the two.'"
