It's a co-star couple!

Us Weekly exclusively confirmed yesterday that Will Forte and January Jones, co-stars on "Last Man On Earth," are dating.

A source told Us Weekly that Forte, 44, and Jones, 37, have been dating for a few months now, and said that the two are "having fun" together.

Neither have ever been married.

We're loving their chemistry on screen, so hearing about their real-life romance off screen is super exciting!

Have fun, you two.
