Before bringing down the house by opening the Oscars with his nominated song from “Trolls” — “Can’t Stop the Feeling!” — Justin Timberlake and wife Jessica Biel talked to “Extra’s” Mario Lopez. Jessica sizzled on the red carpet in gold as she gave Mario the fashion breakdown. “This is KaufmanFranco, this is Tiffany’s and I think It’s cool because it’s distressed and it’s been leaving a trail of sequins wherever I go,” Biel said. "I have a feeling it’s gonna unravel and become a minidress.” "If we need to find our way back home, we’re good,” Justin chimed in. “It’s the Hansel and Gretel of dresses.” He added of the sexy number, “Let’s be honest, we left the house and I was like, 'I win!'” Then he looked Jessica up and down, offering her an appreciative, “Mmm.”
