Meet Debbie, a super spunky lady from Chicago who might just be Rachael's biggest fan. Seriously, even Rach thinks so! She says Debbie is possibly her "biggest fan on the planet Earth."

Debbie's been in the audience of our show more than once, including in season 13, when Rach invited the superfan to try her 60-minute Thanksgiving meal right there in the studio — and followed up the feast with surprise Broadway tickets and a pre-show dinner for Debbie and her husband.

This time around, with the help of beauty and fashion expert Gretta Monahan and Debbie's daughter, Michelle, we gave Debbie a surprise makeover… and much, much more!

First, Gretta woke Debbie up bright and early to surprise her with a glam makeup session at her home in Chicago. After giving her "a New York look," the celeb stylist put Debbie on a plane to New York City to continue the star treatment.

In NYC, Debbie got a stylish wardrobe refresh to go with her makeup. Gretta helped Debbie style not one, not two, but FOUR gorgeous new looks courtesy of J. Crew. Plus, our friends at J. Crew gave Debbie a $1,000 gift card to the store, so she can shop to her heart's content.

Debbie's reaction to the news? "Holy Toledo!"

Watch the video above to meet Debbie and see her amazing makeover reveal. Plus, hear Rachael tell the story of how she and Debbie reunited.

(Spoiler alert: "she lunged at me like a puma," Rach says.) 😂
