Miley Cyrus’ continued effort to prove she “can’t be tamed” spilled into the “Rock in Rio” music festival this weekend, with the seventeen-year-old getting more gratuitously revealing than ever before with her attire.

Trying to succeed as a mature, edgy pop star, Cyrus began shedding her ‘good girl’ image on stage with revealing outfits in concert last year, but her outfit for the Lisbon “Rock in Rio” show took things to a new level. The outfit did not necessarily pay off, however, as it came across as somewhat unflattering for her figure (and, obviously, continues to hurt her tween-friendly image).

Elsewhere, Ke$ha continued to baffle with positively absurd fashion choices for a performance at the MTV Awards in Japan. For all her looks criticism, however, the pop star continues to sell–“Your Love is My Drug” is currently seventh on the Billboard Hot 100 and represents her third solo track to reach the top ten.
