We can only call this a romance that is so back on!
It might just be us, but usually when you're holding hands with someone it DOESN'T mean you're just friends.
Both singers looked fabulously glam, but together they were absolutely show-stopping!
We've been hoping Katy could snag her former beau back ever since she revealed her heart still fluttered for him, so we couldn't be happier to see John realized he'd be freakin' insane to let this dream girl go!
Now, if we can just get them to finally walk a red carpet together!
Ch-ch-check out some other pics of them together before their split (below)!
