According to the Daily Mail, the dinner date might have gone A LITTLE long. The site reports that the exes met up in Beverly Hills for a dinner date over the weekend and they apparently went back to Katy's house afterwards and John didn't leave until 4pm the next day.
That sounds like one heck of a reunion! Maybe they were collaborating on another song together and just got super caught up in their work? Or, maybe they're rekindling their romance.
The couple first went public with their romance in the summer of 2012 and despite frequent engagement rumors, they split in February of last year.
In an interview with Marie Claire while they were still very much "on," Katy gushed, "He's just a fantastic partner. I've been a fan of his for such a long time...He's got a brilliant, brilliant mind. It's a rad, mature relationship."
Hopefully they are rekindling that rad, mature relationship, because we kinda miss them as a couple.
