Dancing with the Stars champ Peta Murgatroyd took her mirror ball trophy and rumored boyfriend, fellow dance pro Maksim Chmerkovskiy, to Las Vegas Saturday.

Wearing the tiniest of tiny bikinis, Peta showed off the hard body that helped her lead her dance partner, football star Donald Driver, to the championship.

She and Maks co-hosted a bash starting the summer season at Encore Beach Club, and partied with friends in a private cabana.

It's no wonder why Maks -- who likes nothing more than taking his shirt off on the show -- can't keep his eyes off of Peta and why rumors started that the two were in an off-screen romance
