Blonde beauty, Amanda Bynes celebrated her 30th birthday on Sunday. The celebration was a low-profile one, held at Six Flags Magic Mountain in California with friends where she was seen enjoying a roller coaster ride and playing games.

“She is doing great,” her family’s attorney, Tamar Arminak, said. “She is happy and healthy, and excited about the future.”

Bynes’ personal life and rehabilitation made her nearly absent from the media all these years. Former Nickelodeon actress had traumatizing life experiences, suffered from mental illness, battled legal issues, shocking tweets. Her previous maniac behavior also resulted in firing her neighbor’s house.

“She seems to still be doing great and seems really focused on school,” a source told E! Online.”We are all so proud of her, and can’t wait to see her amazing designs on the runway someday,” Arminak told Us

Family support and medical health care were the two main factors that helped her get rid out of her traumatic past. Now, she’s been enrolled in Fashion Institute of Design & Merchandising in spring 2014 and just completed her second year at the Los Angeles campus. Prior to this, she had been dismissed on the grounds of giving money to the students to complete her homework and attending school under the influence of Marijuana, Sky News reports.

The actress even got a haircut. “Hi everyone!” Bynes wrote on Twitter to more than 3 million followers on Feb. 23. “I got a haircut! What do you think?” The colour of her hair has changed from purple, brunette and platinum blonde in last two years, Us reports.

“I am doing my best to get better,” the star told Us in a statement via attorney David Esquibias in November 2014. “I am sorry for any pain I caused my family and others … I am thankful for everyone’s patience and understanding.”
