After a rough year in 2013, Amanda Bynes showed off her bikini body while vacationing with her parents this week

The What I Like About You star recently stepped out of the pool while staying in Cabo San Lucas, wearing a neon yellow bikini that showed off her abs and toned body, CelebBuzz reports.

The 28-year-old celebrated her birthday on April 3 in Mexico to take a break from her busy academic schedule.

Bynes recently enrolled at the Orange County campus at FIDM and is studying fashion design. But compared to last year’s unhealthy comments about Drake, she kicked off her new lifestyle by maintaining a healthy body image by eating right and working out.

The owner of Miracles Fitness Retreat in Utah, Austan Torso, told E! in January that the former child star stayed in the facility for a week to start to take care of herself.

“She was interested in getting healthier… to get in better shape, to lose about five pounds but mainly to strengthen up and eat healthier,” he said.

Bynes posted a picture on her Twitter showing off her swimsuit and thanking fans for the birthday wishes.
