The actress resurfaced on Twitter Thursday, to post a brand new picture with her equally stunning sister Jillian.
"Me and my beautiful sister @jillyjoyce," she captioned the sweet candid.
In the shot, the Bynes ladies look super stylish and each are sporting big smiles on their faces. Amanda's rocking a peplum top paired with the black shorts and sexy heels in the candid, while her sister looks just as fashionable in her black top, black leggings and blue sandals.
This is one of the first pictures the former Nickelodeon star has posted since she re-joined Twitter back in April. She previously shared a few snaps from her birthday and FIDIM debut.
