G Kristin Davis purple dress 02/04Kristin DavisSex And The City actress Kristin Davis told a TV talk show host she wouldn't rule out sleeping with a woman during a saucy chat.

The TV star was being quizzed by talk show host David Letterman over fellow SATC actress Cynthia Nixon's lesbian relationship with Christine Marinon.

Letterman asked if Kristin thought Cynthia was a lesbian or whether she was "just visiting".

"I don't personally know but I think she says that she doesn't need a label. Doesn't need one, isn't concerned about it," Kristin said.

Kristin also said she would "never say never" to the idea of having a lesbian relationship one day, despite being straight.

The star recently denied reports she was dating comedian Steve Martin.

"People make things up. It's out of control. I have met him, I auditioned for his movie about a year-and-a half-ago, he's a lovely man but I'm not dating him and I have never dated him," she said.
