She can't stop! Miley Cyrus Shows Fans Her Fake Big Bottom Backstage

Miley Cyrus seems to be making a lot of use out of the new prop for her outrageous stage show.

The 21-year-old singer posted two short videos onto Instagram of her showing off a prosthetic bottom.

The Wrecking Ball hit maker is seen blow-drying her hair while singing, dancing and even twerking backstage before her Bangerz tour date in Monterrey, Mexico on Wednesday. #WATCH video below:

Along with the fake behind, Miley wore a shimmering white top and thong, which really showed off the bodacious behind.

In one of the videos, she runs her fingers through her short, platinum do and said: 'I don't even need wigs b****es.'

Then she proceeds to gyrate her hips to bounce her fake behind up and down before walking through the curtain.
