Are Katy Perry and John Mayer getting back together? The on-and-off music power couple reportedly reunited for dinner over the weekend and have sent rumors flying.

According to E! News, Perry and Mayer -- who called it quits in February 2014 -- were on good terms while they both attended a mutual friend's dinner party on Saturday, Jan. 3. The site reports that the musicians seemed "pretty mellow, relaxed and super friendly" with each other. We love that they're totally comfortable being together in the same setting post-breakup!

Still, just because the two were cordial doesn't necessarily mean they're headed for romance once again -- especially because the 'Dark Horse' singer is allegedly still with DJ and producer Diplo.

In fact, as of New Year's, Perry and Diplo "are still a couple and very much all about each other," a source confirmed to E!

There you have it, Katy Cats. John Mayer and Katy Perry: Friendly exes, but not back together -- for now, at least.
