Does Aaron Sorkin have a new girlfriend? The famed screenwriter stepped out at the 2013 Golden Globes Sunday, Jan. 13 with a beautiful blonde woman on his arm: VHI Morning Buzz host Carrie Keagan.

Though the two didn't pose together on the red carpet, Sorkin, 51, and Keagan, 32, did take plenty of photos together at HBO's annual Golden Globes after party at Circa 55 restaurant in Los Angeles later that evening. The creator and executive producer of HBO's Newsroom dressed all in black, while his date looked stunning in a one-shoulder, red Guarav Gupta gown.

Keagan was named one of Us Weekly's 25 Most Stylish New Yorkers of 2012. She described her signature style to Us as "classy and sassy with a touch of sexy edginess."

Sorkin met Keagan at a junket for The Social Network in September 2010. A source close to Keagan tells Us, "They have known each other for a really long time -- but have been spending more time together recently."

Sorkin was previously dating Sex and the City star Kristin Davis. The two confirmed their romance with a passionate kiss on the lips at the Los Angeles premiere of The Newsroom on June 20. But reports that Davis, 47, and Sorkin split surfaced a couple months later in August.
