'Biggest Loser' contestant stuns Tim Gunn with her new look

It's that time of the year again, "Biggest Loser" fans! Fashion guru Tim Gunn and hairstylist to the stars Ken Paves are back again for the always popular Makeover Week episode Tuesday.

After 13 weeks of dieting and tough workouts, the seven remaining contestants are getting glam head-to-toe looks with help from the pair to show off their new bodies. And in a video that NBC is sharing first with TODAY, it appears that one contestant's transformation is so great even Tim's breath is taken away.

"Good heavens!" the "Project Runway" mentor exclaims when contestant Rachel emerges looking stunning in a sparkly black dress. 

As she stares at her reflection in the mirror, the 24-year-old is moved to tears by her new figure. 

"I honestly didn't recognize you when you came out. I didn't know you had this underneath those sweats!" Tim, who helped select her stylish new duds, enthused.

That's because Rachel's baggy gear had been hiding the results of her 105-pound weight loss.

And if Tim and Rachel are impressed by how good a new outfit makes her look and feel, wait until she gets the new 'do from Ken.

See the complete makeovers when "Biggest Loser" airs Tuesday at 8 p.m. on NBC.
