Amanda Bynes is back—and looking better than ever.

The 28-year-old star was photographed on Wednesday in Cabo San Lucas, Mexico, where she was showing off her bangin' bikini bod in a bright green two-piece.

The blond beauty flaunted her toned and trim figure in a strapless swimsuit, proving her frequent trips to the gym have clearly been paying off.

Bynes, who celebrated her 28th birthday on Thursday, enjoyed a day at the pool while on vacation with her parents, Rick and Lynn Bynes. The recently rehabbed star appeared healthy and happy as she soaked up the sun while spending a low-key day at the beachside getaway.

The She's the Man star, who has been studying fashion, most recently completed her first quarter at FIDM's Orange County campus. She looked amazing at the end-of-quarter event—a runway show on campus that showcased the designs of aspiring student designers—which her parents also attended.

"Amanda is doing great and excelling in her studies," the Bynes' family attorney Tamar Arminak exclusively told E! News. "She is a natural when it comes to fashion and is really enjoying the learning process."

"Her parents and family are so proud of her," Arminak added. "She is an amazing girl."

The once-troubled starlet appears to have transitioned well to her new life, following a tumultuous 2013 during which she spent nearly six months in treatment after being placed on an involuntary 5150 psychiatric hold in July.

In fact, she plans to take more classes this month. "If she was offered an acting job anytime soon, she may not take it because she's so focused on school," a source told E! News.

Bynes has been spotted taking frequent trips to the gym and even kicked off the New Year with a week-long stay at Miracles Fitness Retreat in Utah with a goal of giving her lifestyle a healthy makeover.

"She was interested in getting healthier… to get in better shape, to lose about five pounds, but mainly to strengthen up and eat healthier," owner Austan Torson told us in January.

The celeb has also returned to social media after taking a hiatus for quite some time, providing an update for her Twitter followers on March 1. "Hi everyone! I'm busy studying at @FIDM but I want to say I love you to my fans!," she wrote, in addition to sharing a "new sketch" that is believed to be a self-portrait.

"Amanda's really talented at what she does so the picture is the real deal," a source said. "She's only just beginning."

Keep up the good work, Amanda! You look great.
