Mariah Carey at the 2010 Oscars

Mariah Carey at the 82nd Annual Academy Awards held at LA's Kodak Theatre on March 7.

An elegant look from Mariah and quite conservative - for her anyway. She wore a blue Valentino Haute Couture gown with slit to the leg, masses of silver bling, a metallic Judith Leiber clutch and some gold Christian Louboutin peep-toes.

Mariah's jewelry was a mix of items from Chopard, Fred Leighton and Van Cleef & Arpels.

Mariah and Christina in Red at the SAG Awards

Mariah Carey and Christina Hendricks at the 2010 Screen Actors Guild Awards, held in LA on January 23.

With such similar gown and poses Mariah and Christina were almost like mirror images of one another but acessories and hairstyles ensured each of the curvy stars made the look their own.

Mariah wore sparkling Kwiat jewels, metallic heels and carried a really cute red crystal covered bag.

And Mad Men's resident bombshell, who won a Best Ensemble Cast Award with her co-stars, carried a René Caovilla clutch with her Carolina Herrera gown.

Irit Design jewelry and Louboutin peep-toes completed her look.
