Amanda Bynes debuts new look, joins Instagram

Amanda Bynes is back - again.

The former Nickelodeon star made a rare appearance on Twitter, to inform people she had now joined Instagram. She also debuted a new look with vibrant pink hair and a septum piercing.

Bynes re-entered the spotlight last November with a Paper Magazine cover, but faced another setback earlier this year when she checked back into a mental health facility. In June, she graduated from FIDM and has relatively kept a low profile since.
