Aaron Sorkin dating 'SATC's' Kristin Davis
The pair posed for photographers and Sorkin even planted a lingering kiss on Davis' lips as they walked the red carpet.
The couple was first linked in May and sources say they've been dating for about six weeks.
"They are really happy," a source tells Contact Music. "They have actually known each other a while through mutual friends and would sometimes bump into one another at industry events, but it has only just turned into something more."
Sorkin was previously married to Julia Bingham, with whom he has a 12-year-old daughter, Roxy. Davis has never been married, but last year she adopted daughter Gemma Rose as a single mom.
