Eight years after stepping away from Project Runway in 2017, the supermodel is returning as host for season 21 of Freeform's fashion competition series .

"It feels so amazing to be back," Heidi exclusively told E! News' Will Marfuggi during the July 30 episode. "It really feels like coming home."

As for why she decided to return? In addition to reuniting with longtime fellow judge Nina Garcia and season four winner turned host Christian Siriano, Heidi gets to rub elbows with new judge, A-list stylist to the stars Law Roach.

"And then doing this with Law," the 52-year-old continued, "and obviously Nina, we've known each other for so long, Christian Siriano. And just having these 12 amazing, talented designers on the stage, it's just the most fun thing for me to watch and be part of."

And Heidi's return to the catwalk was a major reason Law signed on to give his industry expertise to the new designers.

"To hear Heidi was back, it was like, 'Okay, this feels good,'" Zendaya's right-hand man told E! News. "'This feels like history.'"

When it comes to the season 21 drama, Nina teased some designers weren't so receptive to the judges' critiques.

"The competition is tight, but I also think the judges, we are really telling them honestly how we feel," the Elle magazine Editor-in-Chief promised. "And some take it well, some don't."

As for this season's celebrity guest judges—which include Tyra Banks, Nikki Glaser, Zac Posen and Sara Foster, among others—Heidi was most excited to welcome her former fellow America's Got Talent judge Sofía Vergara.

"I was so happy that she said yes, because she's wearing, ultimately, the winning look," Heidi shared. "I said to her, 'If you really hate it, I'm just gonna have to wear flats every time when I see you,' because she hates being shorter than me. She's always like, 'Klum, take those heels off.'"
