Ready, set, glam!

They've gone through the grueling workouts, and now the contestants on NBC's The Biggest Loser will get a chance to relax and revamp their looks on the show's annual makeover episode, airing May 3.

On hand to help the remaining contestants spruce up their style? Fashion expert Tim Gunn and celebrity hairstylist Ken Paves!

Gunn -- who will lend his talents as a fairy godfather of sorts in the Cinderella-themed episode -- tells exclusively that the contestants he styled were ready to make a change.

"Everyone thinks with their own aesthetic, but [they] put their preferences on the shelf and said, 'Tim I am part of your fairytale, let's do this together.' We had a blast."

Paves was just as thrilled to offer his services to the contestants.

"It's so gratifying," Paves tells Us. "I have the luxury of reintroducing women to themselves [when] they've forgotten how damn special they are. When you can take a woman like that and make her look so special, and she looks in the mirror and likes what she sees...that's the greatest part of what I'm doing and what I get to do."

The Biggest Loser airs Tuesday at 8 p.m. (EST) on NBC.
