Miley Cyrus shows off her toned abs in the promo for the next episode of Rihanna's reality show Styled To Rock.

The 20-year-old was assigned to judge a fashion design competition during a guest appearance.

In the clip, host Erin Wasson tells the contestants they will be working with one of the "hottest, young trendsetters" in entertainment. The contestants gasp when they are joined by Cyrus, who says she "can't wait" to see what they create for her.

Co-host Mel Ottenberg puts more pressure on the aspiring fashion designers when he informs them that "one other important person in the mix" will co-judge alongside Cyrus--her momager Tish Cyrus.

The clip cuts to a scene where one contestant announces that she "pretty much sketched out [a design where Tish's] daughter is a whore." The teaser also reveals that the competition heats up among the contestants. Cecilia tells Dexter that she overheard Sergio saying she is "hogging the leather." Sergio, who is visibly upset, tells her he can hear their conversation about him.

"Excuse me? Don't you know I'm sitting here?" he yells and begins to walk over to confront them. 

Cyrus' appearance follows previous celebrity guests, including Kelly Osbourne and Kylie Minogue. Her episode on Styled To Rock will premiere on Friday, Nov. 15 on Bravo.

It will air several days after she sparked controversy at the 2013 MTV Europe Music Awards held on Nov. 10. When she arrived on stage to accept the Best Music Video award for Wrecking Ball, she pulled out a rolled-up cigarette that is rumored to be marijuana and smoked it during her acceptance speech.
