Saturday at 10PM, Brenda will make a guest appearance on MTV's Styl'D, a show that follows five junior stylists working for the Margaret Maldonado Agency.
Drama goes down when one of the stylists has Brenda try on an Alexander Wang strapless dress for the 'Transformers' premiere that Demi Lovato and Rihanna already wore. Major fashion no-no.
"Oh, that makes me worried a little bit because there's always that 'Who Wore It Best?' thing," the Disney star says.
Brenda isn't the only celeb having fun trying on designer clothes tonight. Sean Kingston takes his turn this episode as he tries to find the perfect look for a PETA public service announcement. And Brenda's BFF Ashley Tisdale will make an appearance on the show's season finale on January 2 where she'll get styled, along with The Veronicas.
Check out the preview below where one of the stylists falls into a the pool while helping Brenda put on her shoes!
