Kristin Davis and screenwriter Aaron Sorkin have split after just a few months of dating.

The Sex and the City star was first linked to Sorkin in May and they went public with their relationship a month later, making their debut as an item on the red carpet for his new TV show The Newsroom.

However, the pair has now reportedly gone its separate ways.

A source tells In Touch, "They're very different people. She's focused on raising her daughter, Gemma, and he's working on his show. They'll definitely remain friends."

Davis adopted little Gemma Rose as a single parent earlier this year.
