Like her fellow Disney divas Miley Cyrus and Vanessa Hudgens, Demi Lovato seems to be on a mission to prove she's all grown up now.
The 17-year-old Camp Rock star sported what appeared to be a tattoo while on vacation with her family in Cabo San Lucas, at the Casa Dorada Los Cabos Resort in Mexico Wednesday, and RadarOnline.com has all the pictures for you.
Lovato wore a teal bikini and brandished a floral design under the right-hand side of her chest. She was seen enjoying a ride on a sea doo water scooter on the sunny summer day.
We're not sure whether to buy that the tattoo is real, as Lovato Tweeted last year that she loves to fool the press sometimes with her youthful antics.
"Hahahaha some people are so stupid. So what? I like to draw on myself," she Tweeted in July 2009. "Sue me. Hahaha I’m 16 I’m not getting a tattoo anytime soon. Oh my gosh, not STUPID but I’m just saying people should get their facts straight! Hahaha I’m not mad I just think it’s funny. Man I can’t say anything on this thing! Haha."
