After all the bad wigs and facial piercings, Amanda Bynes is making a complete transformation in the fashion department. Sexy photos of the actress in a bikini were leaked while she was on a family vacation to Mexico, indicating that enrolling in fashion school and continuing with her mental health treatment has also contributed to a healthier outer appearance. The trip was a present from her parents to celebrate her 28th birthday while on spring break from fashion school.

Bynes' doctors reportedly told her that daily exercise was a major part of regaining her balance and calm. It appears that she has been following doctor's orders . She has regularly been spotted out on walks with her family and showed off a toned body in the sexy bikini pics.
