We don't have to tell you whose siblings these adorable kiddies belong to. But just in case you don't know— Frankie, 8 is the little Jonas bro and Noah, 9 is the little sis to sassy n' sweet Miley. The families of the two are already grooming these cuties for the limelight starting with Ponyo. The lil' duo who are already good friends recently premiered the flick in Los Angeles. We bet Frankie and Noah will charm the press just like their older supportive successful sibs.
