Well, nobody saw this coming!
Well... it's who he left the club with that's causing a stir:
Katy Perry's sensational new single clawed its way to the top of the supreme Hot 100 chart!!!
Overtaking Robin Thicke's Blurred Lines at #1 on Billboard's Hot 100, KP's Roar is officially king of the jungle!!!
Way to go, gurl!! You did it!!! We're so very proud!!!
Amazingly enough, KatyCats, this marks the 28-year-old's eighth Hot 100 number one! EIGHTH!!!
Incredible!! She has come so far since 2008's I Kissed A Girl, we barely believe it!!!
We can't wait for number nine!!!
