Frankie Jonas

For every David Cassidy, there was a Shaun; for every Jessica Simpson, an Ashlee. Hollywood was peppered with celebrities who broke out of their older siblings' shadows to become a star in his or her own right. Frankie Jonas was no exception. He gained popularity by being the youngest brother of pop stars The Jonas Brothers, even being given the nickname "the Bonus Jonas" by millions of fans. He soon became a fixture in the band's family-based entourage, appearing in the 2009 film "Jonas Brothers: The 3D Concert Experience" and getting rave reviews for his adorable performance in the sitcom "Jonas" (Disney Channel, 2009-10). Jonas may have grown up a rocker-in-training, but with each appearance and project, there was no denying he, himself, also had the makings of a star.
