Amanda Bynes just pulled a Rihanna ... with her hair!
The actress debuted a brand new 'do last night on Twitter, posting a photo of her with half her head shaved.
While RiRi and Avril Lavigne have both rocked the look, Bynes revealed her half-shaven inspiration was actually a different singer: Cassie.
"I buzzed half my head like @cassie! No more old photos! This is the new me! I love it," she tweeted along with the photo.
It's definitely a different look, but an improvement over the mess of extensions she was sporting on her head before.
The move is only the latest in a string of strange behavior from the 27-year-old, who has started bashing anyone online who uses unflattering photos of her or writes unfavorable stories about her.
Check out some of the Amanda-approved photos from her Twitter page above.
