Beyoncé Knowles made a quick cameo on Series Six of 'Britain's Next Top Model' on Monday night (August 2) to delegate a new challenge to the show's 10 remaining contestants.

Tuning in from a video feed, Mrs. Carter explained the details of her assignment, which required the girls to film a new commercial for her Heat fragrance. B's stipulations for the shoot centered around having the girls convey a "strong, sexy and powerful image" on camera.

The successful singer and entrepreneur recently explained the basis of her fragrance, emphasizing that it was intended to inspire strength in her female fan base. "I wanted this to be something that made you feel like you could conquer anything, and take over the world," she said. "Strength was something important, because a lot of my songs I write for my women, to empower them."
