January Jones and Will Forte Break Up

Co-stars decide to call it quits after five months of dating

Will Forte and January Jones are back to just being co-stars.

E! News has learned that The Last Man Standing pair have called it quits after dating for five months. No details surrounding their break up have been revealed. E! News has reached out to reps for comment.

It was first revealed that Jones and Forte took their chemistry off-screen back in April.

The twosome, who first worked together when the Mad Men star hosted Saturday Night Live in 2009, currently star on the Fox comedy about a guy (Forte) who thought he was the last man on Earth until he met Carol (Kristen Schaal) and married her. Then, he realized there's another woman roaming around—Melissa (Jones)!

And, well, he was just in awe of her (both on and off screen, apparently).

While promoting her big-screen project Good Kill at the Tribeca Film Festival in late April, Jones stayed mum and wasn't ready to reveal too many details about her personal life.

"I'm looking forward to a break," she told E! News at the screening. "In a couple of weeks, I'm going to take a vacation and relax on the beach somewhere under an umbrella."

Jones split from Sweetwater director Noah Miller in January 2013 and has previously dated Adrian Brody, Jeremy Piven and Forte's former SNL co-star Jason Sudeikis.

Us Weekly was first to report the split.
