Oscar-winning screenwriter Aaron Sorkin and Sex and the City star Kristin Davis have reportedly called it quits. According to In Touch, the couple has parted ways just two months after they stepped out together at the premiere of Sorkin's HBO drama The Newsroom. "They're very different people," a close pal tells In Touch. "She's focused on raising her daughter, Gemma, and he's working on his show." News of the romance between Sorkin and Davis broke in May, but the two had known each other for years. Despite their breakup, the source assures, "They'll definitely remain friends."
