Young Hollywood crashes yet another "Dancing With The Stars" rehearsal, this time with the star of Disney Channel's 'Zombies', Milo Manheim, and his pro partner Witney Carson! The young actor talks about what it was like growing up on sets his whole life (thanks to being the son of award-winning actress Camryn Manheim), plus he gives us the scoop on teaching the Kardashians how to play Poker before teaching us a little Salsa!
