"Sex and the City" actress Kristin Davis is in the early stages of a relationship with Oscar-winning screenwriter Aaron Sorkin, according to E! News.

A source says they've been dating for about six weeks, adding, "They are really happy. 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."

The 50-year-old Sorkin, whose recent screenwriting credits include "The Social Network" and "Moneyball," was married to Julia Bingham from 1996 to 2005, and was later romantically linked to actress Kristin Chenoweth.

Davis, 47, has never been married.
