It looks like "Last Man on Earth" co-stars January Jones and Will Forte have chemistry on and off the screen. Us Weekly is reporting that the pair, who most recently played lovers in "Last Man on Earth," are casually dating and have been for quite some time now.

Jones previously revealed to Us she was a "huge fan of Will," and thoroughly enjoyed working with him on the set. The "Man Men" star told the magazine she "got to go to work and laugh my a-- off." 

Their relationship is not believed to be serious at the moment. The report says Jones' new beau is "a good guy" and that the rumored pair are "having fun" together. The two have appeared on red carpets together but played it cool and kept a casual distance. Relationship rumors began swirling following the "Last Man" series wrap party Feb. 24, where an "insider" claimed they were seen spending a lot of time together.

"It's very new," the source told Us. "They're seeing where things go."

This is not Jones' first high-profile relationship. The 37-year-old, who recently appeared on the cover of Rhapsody magazine, has previously been linked to director Noah Miller, Jason Sudeikis, Ashton Kutcher and singer Josh Groban. Forte, 44, on the other hand, has not been linked to any famous females since rising to fame in 2002 on "Saturday Night Live." He played Bruce Dern's son in the critically acclaimed film "Nebraska" in 2013.

Jones is preparing for the airing of the final episodes of AMC's "Mad Men." She is believed to be working on a new show alongside Forte, though there are few details about the project at the moment.

Although the New York Daily News reached out to both actors' reps for comment, neither has responded to the relationship rumors.
