January Jones is reportedly dating her Last Man on Earth costar, Saturday Night Live alum Will Forte.

January Jones & Will Forte Dating?

Jones, 37, and Forte, 44, have been dating for a couple of months, an insider told Us Weekly. “He’s a good guy,” the source told the outlet, adding that the new couple is “having fun.”

Jones and Forte are thought to have met while filming the first season of apocalyptic sitcom Last Man on Earth, which also stars comedian Kristen Schaal. In the series, Forte plays 40-year-old man-child Phil Miller living in Tuscon, Ariz., who thinks that he’s the last man alive after an unspecified apocalypse. Before long, Schaal’s Carol arrives in Tuscon, followed by Jones’ character Melissa.

The Mad Men actress, who has never been married, has a three-year-old son named Xander, whose father she’s never identified to the public. Jones has previously been linked to Jason Sudeikis, Ashton Kutcher and Josh Groban. Her last high-profile relationship was with director Noah Miller, which ended in 2013.

Forte, who has never taken a romantic relationship public, joked a number of years back about how he tends to fly under the radar despite his relative fame. “I’m kind of under the radar. Not a lot of people notice me,” Forte told the A.V. Club. “Which is surprising, because I’m so sexy. They’re probably intimidated by my sexiness and crushability.”
