Hudgens, 22, rose to fame starring in the "High School Musical" films with then-boyfriend Zac Efron and can be seen in the upcoming action-fantasy movie "Sucker Punch."
Her ad campaign for Candie's is set to debut in March. Britney Spears and Fergie of the Black Eyed Peas have also been spokesmodels for the brand, whose products are available at Kohl's department stores in the United States.
"Ever since I saw Fergie do the ads for Candie's, I fell in love," Hudgens said in a video posted on the Candie's Facebook page. "It's such an honor to be able to be a Candie's girl now."
"Sucker Punch" is directed by Zack Snyder and due for release on March 25. Hudgens plays Blondie, a girl who is put in a mental institute and imagines herself as a prostitute in a brothel in order to cope with it.
The movie also stars Carla Gugino of "Watchmen" and "Entourage" fame as well as Jon Hamm from the drama series "Mad Men."
