In the sexy snapshot, the 21-year-old "Neon Lights" singer lies on her stomach in only a barely there thong bikini while tanning. At the forefront of the pic is Lovato's gorgeous makeup-free face and cleavage while behind her is her curvaceous backside and legs! The whole photo is accented by rays of light shining over the former X Factor judge's body.
Lovato captioned the sexy bikini pic with, "When in Brazil......#NEONLIGHTSTOURSA."
Lovato also shared a scenic shot of the Brazilian coastline and ocean. "How gorgeous is Rio?? #NEONLIGHTSTOURSA," Lovato wrote with the beautiful beach pic. The touring pop star added, "Brasilia you were on FIRE tonight... I love you!!!!!"
Lovato covers this month's issue of Cosmopolitan for Latinas. In the issue, she opened up about her troubled past and wanting to be a role model for young girls.
"When I was younger, I needed someone in the spotlight to idolize, who stood for positivity and light and happiness, and wanted to change the world," she revealed. "And because I didn't have that, I realized, I want to do that, if only for my 12-year-old little sister."
