'WWHL': Karlie Kloss talks Taylor Swift and converting to Judasim before marrying Joshua Kushner

New "Project Runway" host Karlie Kloss was on "Watch What Happens Live" on Thursday night following the show's season 17 premiere, and she opened up about a variety of hot topics in her life, including husband Joshua Kushner and her friend Taylor Swift.

Throughout the show, fans submitted questions for the model, including one about her top-secret wedding to Joshua Kushner -- brother of Jared Kushner -- back in October, which nobody in the public knew was happening until Kloss posted a photo from the ceremony on Instagram. The fan wanted to know who the hardest person to keep her wedding a secret from was.

"I mean, my wedding was really special and all the people nearest and dearest to me knew," she said matter-of-factly.

As a follow-up question, Cohen read another fan inquiry where someone wanted to know if the St. Louis-native converted to Judaism before her nuptals, just like sister-in-law Ivanka Trump.

"I joined the tribe," she said while raising her glass. "Mazel!"

In addition to sharing a few details about her intimate wedding, Kloss also gushed about Swift, who she's been friends with for years, but -- because the two busy celebs don't hang out publicly as much as they used to -- about whom she's had to fend off countless questions about.

"Taylor's incredible, and I feel really lucky to call her a friend and she's one of the hardest-working women," Kloss said when asked about Swift's recent essay for Elle magazine. "I loved her essay."

When Cohen added that Swift could "poop out" hit songs, Kloss laughed and responded, "She can sneeze it out. She is so talented. So talented."

At last week's premiere party for "Project Runway," Kloss told AOL that she would love to have Cohen appear as a guest judge on the design competition show at some point.

"I think Andy Cohen would be a great guest judge," she said. "I think he would be fierce and very opinionated. He’s such a pro. He loves the show, and I think we should have him on as a future guest!"
