Miley Cyrus and Robin Thicke were unstoppable at VMA night!

The 20-year-old singer left the crowd agape as she stormed the stage at MTV Video Music Awards 2013 with a racy duet with  Thicke. For once, Miley made even Lady Gaga look tame, as she twerked and stroked at Thicke's crotch with an oversized foam finger, during their performance.

Featuring a bunch of dancers in crazy bear dress, Cyrus, a fiery ball of energy, stepped onto the stage in a fuzzy gray leotard, shaking her booty to her racy number 'We can't stop'.

During the crazy six-minutes she spent on stage, she shaked her butt at the audience, stripped down to a nude-colored bra and matching underwear, and even slapped the butt of another woman dancer.

The 20-year-old star was soon joined by the 'Blurred Lines' hit maker Robin. She bewildered the star as she shook her rear on his groin, leaving the audience jaws-dropped.

Cyrus and Thicke's performance led in tweets per minute peaks with 306,100.
