"Hi everybody! I haven't tweeted in a long time and I want to say hi! I've been really busy at FIDM, and I just finished my midterms," read the first tweet from Bynes, who first enrolled at the Fashion Institute of Design & Merchandising in 2014 and returned to her studies last fall.

"I am really loving school and I feel that I am learning a lot," she tweeted moments later. "I enjoy all of my classes and my teachers are excellent."

The "She's the Man" star then offered up an explanation for her Twitter disappearance. "I'm really appreciative of all that FIDM is giving me. I've been in school learning about the fashion business so I don't have time to tweet," she said.

It's not unusual for Bynes to slip in and out of social media. The "Easy A" actress last tweeted in February, showing off a platinum blonde shoulder-length haircut.
