For Dylan Efron, using brother Zac Efron's song during Dancing With the Stars' Dedication Night was a no-brainer. "It just made sense," Dylan, 33, exclusively told Us Weekly after the Tuesday, October 14, episode. "It wasn't even a thought. That's like my favorite performance by Zac, so it was special." Dylan and partner Daniella Karagach performed a contemporary routine to Zac and Zendaya's song "Rewrite the Stars" from The Greatest Showman.
