Watch Miley Cyrus Totally Take Over Mike Will's SXSW Gig

She Super Soak'd it.

Worst kept secret in Austin. That's pretty much all you can call Miley Cyrus' surprise appearance at the Fader Fort on Thursday night. Nobody was complaining, but from the looks of it pretty much everyone knew something major was gonna happen during Mike Will Made-It's set.

Armed with a Super Soaker, Miley stormed the stage, performing "23" and "We Can't Stop" and joining Future and Rae Sremmurd on "Throw Sum Mo." The gig, billed as "Mike Will Made-It and Friends," also featured Riff Raff and Two-9.
