Viva la diva

Three decades and a whole world of sex separate them. But when it comes to promoting a record, they both know the name of the game -- get on the road and shake that money maker.

This weekend, the princess of cross-over bubble gummy pop and the grand dame of dance- and radio-ready music took to two very different stages, Miley Cyrus at the tween-friendly shriek-heavy KIIS-FM-backed Wango Tango and Madonna at the U.K.'s Radio 1 Big Weekend.

Each showed off her respective assets, but if it hadn't been for a feat of wardrobe engineering, multiple Grammy-winning ripped superstar Madonna's could've come popping right out of her bustier. Hey, are those new?

Aside from the wild bed head and rocker stance, Miley continued to try to buff her wholesome girl-next-door image and regain the trust of suspicious soccer moms everywhere by covering up (no cleavage here!). There was nary a satin bed sheet to be found anywhere at the Irvine stadium.
