Kristin Davis and Steve MartinKristin Davis and Steve MartinSex And The City's eternal singleton, Kristin Davis, looks to have finally found herself a fella.

And like Carrie Bradshaw in SATC with her Aleksandr, Kristin's new man is a tad older.

It's comedian Steve Martin whom Kristin's rumoured to have fallen for - despite a near 20-year age gap.

A friend who saw them at a pre-Oscar party told New!: "It's the real thing. They are ready to let people know they are an item.

"They tried to act like they weren't together at the party, but couldn't stop stealing kisses."

Roxanne star Steve, 59, apparently threw Kristin a surprise 40th birthday bash at his LA home.

Kristin, 40, has previously dated Alec Baldwin and Jeff Goldblum, but has never married.

Kristin's not as prim as character Charlotte in real-life - but, all the same, she asked her mum, a feminist, never to watch SATC.
