After hospitalization and six months in a private rehab facility, Bynes seems to have gotten her life back on track. She enrolled in classes at the Fashion Institute of Design and Marketing and is often seen on her way to the gym.
She deleted all her previous tweets, changed her profile pic and has tweeted only twice this year.
"Hi everyone! I'm busy studying at @FIDM but I want to say I love you to my fans! Xoxo Amanda," she wrote March 1.
