'Victoria's Secret Fashion Show' Sneak Peek: 'House of Style' Chills Backstage!

Justin Bieber, Rihanna and Bruno Mars will all perform during the show, airing Tuesday at 10 p.m. ET on CBS.

Can't wait until Tuesday (December 4) night to watch the Angels strut down the catwalk in lingerie during the Victoria's Secret Fashion Show? Well, MTV's very own "House of Style" was on hand when the show taped back in November and they've got the backstage scoop. The show's latest episode offers up a sneak peek at the big production.

The episode includes some killer behind-the-scenes access to seeing the models get ready, including both the show's hosts, Karlie Kloss and Joan Smalls prepping to walk down the runway to the tunes of Justin Bieber, Rihanna and Bruno Mars.

"I remember all of us being in our living room watching the Victoria's Secret Fashion Show," Kloss reminisces in the episode.

Fellow host and Angel, Smalls recalled always wanting to be a part of the dazzling fashion show, which features the bodacious models showing off some of Victoria's best-kept lingerie secrets, complete with rhinestones, gemstones and crystals. "I always remember wanting to be in the show because it was so dreamy and fabulous," she says. "And every woman in the show is so beautiful."

So, what does it take to get VS hot? Kloss dishes, "A lot of hair extensions required, a lot of tan experts back there, and whole lot of ... Victoria's Secret, that's what it takes, a whole lot of help."

The full show airs on CBS at 10 p.m. ET and the show got some early buzz thanks to the performances from Bieber, Mars and Rih. It also made headlines after Bieber was romantically linked to model Barbara Palvin. The rumors kicked off shortly after they taped the show, later leading to his short-lived break-up with Selena Gomez.

With the gossip behind them, fans can now check out all of 2012's most eye-catching, barely there fashions and finally get to see the trio of pop superstars belt out their greatest hits (new and old) alongside the models. "It's like the Olympics," Kloss says. "I feel like girls train for this like they do for the Olympics."

So, how do the models end up looking so fab alongside the pop stars enlisted to perform year after year? Along with spray tans and hair extensions, fake eyelashes and makeup are all used to doll up the already beautiful ladies. Karlie says, "Smoke and mirrors, baby, smoke and mirrors! But most important, the most important thing you can wear on that cat walk is..."

"...confidence," Smalls added. "It goes a long way."
