John Legend can do know wrong.
Seriously, we don't know how the All of Me singer delivers a killer performance EVERY SINGLE TIME!
Check out the Legend's patriotic performance (above)!
Good news, Katy Cats!
America's favorite California gurl hasn't settled down yet!
She wasn't the only A-lister in attendance, either!
Leonardo DiCaprio, Kevin McHale, and Luke Haas were there rockin' the Casbah, too!
Leo and Kitty Purry together at the same shindig? AMAZEBALLS!
