How did Kelly Ripa prepare for her interview with Kristen Stewart? By reading the Hot Bodies issue of Us Weekly, naturally!

"To me, it's the Bible, so I believe everything I read in this magazine," Ripa, 41, told Snow White and the Huntsman's Stewart, 22, during LIVE! With Kelly Thursday.

"Oh, cool," Stewart said, gazing at a full-page feature on her shoe swaps. "Everyone else, you should, too!"

Ripa then zoomed in on the Hot Pics feature, saying: "I've noticed this trend and I think on you it's adorable. You wear high heels walking the red carpet, but then you change into sneakers with your formal wear."

(Stewart ditched her Brian Atwood pumps for Vans last November, and she traded her Jimmy Choos for Nikes just two weeks ago.)

The morning's guest co-host, ESPN's Mike Greenberg, 44, then inquired: "Where do you carry [the sneakers]? If you're on the red carpet, do you have someone carrying those, or are those in a bag of some kind?"

Stewart laughed and replied, "I've got someone carrying them." She then joked, "I'm just trying to be different! Just trying to be cool!"

Though Stewart is sometimes criticized for her grungy-glam style, Ripa understands her need for comfort. "After you sit down for a while, your feet start to swell," she said. "And it feels so uncomfortable to get up and walk on those heels!"
