Beyonce Knowles has been banned from shaking her famous bottom on the set of new film Dreamgirls because she might tear her expensive outfits. The star, famous for 'shaking it' in videos such as "Work It Out" and "Crazy In Love," has been told by costume designer Fatima Robinson to tone down her famous booty-shaking dance moves.

Robinson warns, "I said you can move it, but don't shake it!"

Set in the turbulent 1960s to mid-70s, "Dreamgirls" follows the rise of a trio of women -- Deena (Knowles), Effie (Jennifer Hudson) and Lorrell (Anika Noni Rose) -- who have formed a promising girl group called The Dreamettes. At a talent competition, they are discovered by an ambitious manager named Curtis Taylor, Jr. (Jamie Foxx), who offers them the opportunity of a lifetime: to become the back-up singers for headliner James "Thunder" Early (Eddie Murphy).

Curtis gradually takes control of the girls' look and sound, eventually giving them their own shot in the spotlight as The Dreams. That spotlight, however, begins to narrow in on Deena, finally pushing the less attractive Effie out altogether. Though the Dreams become a crossover phenomenon, they soon realize that the cost of fame and fortune may be higher than they ever imagined.
