Top 15 teen stars with the hottest bikini bodies – You need to see number 1! (With Pictures)

4. Demi Lovato

Demi Lovato is also one of the girls that have grown up too fast. She is doing her best on the radio, but you will agree she is doing just fine on the beach, as well. Demi is killing that black bikini and she is no longer afraid to show some more skin. She also hosted a pool party last summer to celebrate her new single Cool for the Summer, and as you might expect she was the center of attention, but not because of the single, but because of her small bikini top. After years of battling with body issues she is finally showing much more, and we are all pretty happy with what we see.
