Miley Cyrus' changing looks never fail to get a reaction.
Her latest pose, in which she appears topless except for star-shaped pasties, wearing a blonde wig and false protruding teeth, is no exception.
As always, there's a reason behind her new look. Posting the photo on Instagram Monday, Cyrus wrote, "@MTV PRESENTS MILEY CYRUS: MTV UNPLUGGED YALL check it out January 29th!"
The 21-year-old pop star and MTV's Best Artist of 2013 will be performing more intimate renditions of her biggest hits, including "We Can't Stop" and "Wrecking Ball," without amps or beat machines. Of course, this being Miley, anything can happen, and MTV promises that there will be surprise guests joining her.
In recent years, the "Unplugged" series has featured Katy Perry, Adele, Adam Lambert and Lil Wayne, among other artists.
Cyrus's special will debut less than three weeks before she launches her "Bangerz" tour February 14 in Vancouver, Canada.
