Is Amanda Bynes The Next Celebrity Headed For Rehab?

Amanda Bynes was arrested on April 6th for drinking and driving, and continues to go clubbing. After her release form jail, Bynes has been seen partying, texting and driving, and even and crashing her car into a curb.
Her father Rick is in denial about her arrest, "She was not drunk. I was told that she blew a zero on the Breathalyzer. She didn't have a single drink that night. My daughter doesn't drink."
Back in March, A TMZ photographer saw a drunk Amanda leave Greystone and told the valet she was not able to drive home. The valet gave her the keys anyway. 
Sources are saying Amanda isn't addressing her drinking as a problem yet even though her friends are worried. Should Amanda go to rehab?
