Beyonce and Mariah Carey have a lot in common — they’re both gorgeous, monumental stars reigning the music world with their fabulous curves and powerhouse voices. Apparently, they also share the same taste in fashion! The lovely ladies were seen rocking the same black, formfitting Roberto Cavalli gown. So which curvaceous diva wore it best?

Let it be known that Beyonce did get her hands on the dress first. The ‘Pretty Hurts’ singer chose the luxe black gown with lace cutouts for her appearance this past February at the Pre-Super Bowl DirecTV Super Saturday Night event in New York City. She paired the outfit with a pair of platform stilettos and loose, wavy curls, achieving an overall glamorous look.

Mariah chose her own version of the Cavalli dress for her performance at the World Music Awards in Monte Carlo on May 27. The ‘You’re Mine’ singer, who received the Pop Icon award at the event, made a few alterations to the dress to truly make it her own. The plunging neckline is the most noticeable difference, showing that Mariah went for sexy over glam. We’re not sure what her fingerless black glove indicates, but that’s a definite change from Beyonce’s look, too.
