Amanda BynesAmanda Bynes wants her acting career back.

Just a month after tweeting she was done with Hollywood, she tweeted simply, "I've unretired."

Her next tweet shed no light on her decision. It only served to promote her next movie, 'Easy A.'

"easy A. September 17th. check it out :)," she wrote.

Bynes used her Twitter account similarly to announce her retirement in June. "I know 24 is a young age to retire but you've heard it here first. I've #retired."
