Sexy Celeb Alert! Demi Lovato Sizzles In A Thong Bikini

This former X-Factor mentor is anything if not flexible.

The 21-year-old beauty adapted to the local culture in Brazil comfortably and decided to do what the Brazilians do while in Brazil — wear a thong bikini.

The singer looks stunning in the Instagram photo that she posted to document the affair and we are happy she did. Looks like she is having a good time while on her South American leg of the Neon Lights tour. We are so jealous. Will you take us with you on your next tour, Demi? Pretty please?
