7. ‘Alejandro’ – Top Lady Gaga Videos

In ‘Alejandro,’ from 2009’s ‘The Fame Monster,’ Gaga tries to push as many buttons as possible by combining the often-controversial topics of sex and religion.

The nine-minute clip features Lady Gaga dressed as both a platform heel-wearing nun who swallows rosary beads and a wannabe dominatrix who manhandles men who wear high heels. She also wears a gun bra and gives a nod to Madonna with a black-and-white scene, in which Gaga dances around wearing long pants and a black vest, recalling the ‘Vogue’ video.
