"Sex and the City" actress Kristin Davis is dating photographer Russell James, People reports. "It's been going on for a bit now," a source tells the publication of the twosome, who hasn't publicly acknowledged their romance just yet. "She's very supportive of him - she seems very happy."

It is reported further that Kristin and Russell were seen on July 20 enjoying a dinner date at Katsuya Brentwood in Los Angeles with a friend. Both of them were said sitting in an intimate booth and acting very affectionate toward each other. Later that night, she was also seen resting her head on his shoulder. "She was all smiles," a witness tells People, adding "A little giddy."

The in-love pair was then spotted walking out of the venue quietly, "trying to keep a low profile." Kristin grabbed Russell's hand for a second as they made their way out of the eatery.

Though there has been no word from either Kristin or Russell, dating speculation has sparked since last month. She reportedly joined him at a party held at the grand reopening of Santa Monica's Shangri-La hotel to celebrate his new photography book. "They hung out at the party and were definitely a little flirty even in public. They seemed like an item," an onlooker said at that time.
