Amanda Bynes's road to recovery has definitely been successful so far.

The 28 year-old has taken a vacation to Cabo San Lucas, Mexico, for Spring Break as well as her birthday and she seems to be enjoying every minute of it.

Bynes, whose birthday was on Thursday (April 3rd), took to Twitter to give special thanks to her fans for their well wishes and kind messages.

"Thank you everyone for all the birthday wishes," she tweeted, along with a photo of herself smiling, while sporting a lime green bikini top and matching bottoms, topped-off with a pair of black flip-flops.

The importance of the photo shows the blonde beauty looking healthy and happy after having a very turmoil time personally, last year (2013).

Bynes posted another photograph, on the social media site, of herself working on her tan while chilling at the side of a pool. This was simply captioned: "Spring Break."

The former Nickelodeon star has completely turned her life around after coming out of a near-6 month stay at a rehabilitation clinic late last year.

Byne's behaviour had become very bizarre last summer, and she began to have run-ins with the law for several incidents, which includeded an offense for tampering with physical evidence after throwing a bong out of her apartment window in NYC.

The former 'Amanda Show' star also got arrested for setting fire to an elderly woman's driveway, she was held in a psychiatric hospital to undergo treatment for bipolar disorder and schizophrenia.
