Kristin Davis and her Sex and the City character, Charlotte York, may have both been unlucky in love at one time or another, what with divorces and her tawdry photos getting leaked and all. But Davis has found a match in Russell James.

"It's been going on for a bit now," says a source close to the actress and the celebrity photographer. "She's very supportive of him – she seems very happy."

On July 20, the pair joined another pal at Katsuya Brentwood for dinner in Los Angeles. Russell James and Kristin Davis, 44, sat in an intimate booth.

Davis rested her head against his shoulder.

"She was all smiles," says the onlooker. "A little giddy."

The duo walked out quietly, trying to keep a low profile, with Kristin Davis grabbing Russell James' hand for a second as they headed up the steps.

In June, Davis joined James at a party to celebrate his new photography book at the grand reopening of Santa Monica's Shangri-La hotel.

"They hung out at the party and were definitely a little flirty in public."

"They seemed like an item," said an observer at the time.
