Miley and Mandy star in their own version of Madonna’s 4 Minutes.

We just found this brand new video of Miley and Mandy remaking Madonna, Justin Timberlake and Timbaland's "4 Minutes" music video, complete with back-up dancers.

Miley Cyrus, Mandy Jiroux and co look like they had a blast making the video, and watching those amazing break dancers makes us want to learn how to do some of their tricky moves.

We wonder how long it took everyone to learn the dance?
