She's got the bombshell look down pat!
The 21-year-old model, who rose to fame after starring in the Carl's Jr. Super Bowl commercial, was photographed by Miguel Reveriego in Beverly Hills, Calif. for the Old Hollywood glamour-style shoot.
In the behind-the-scenes video teased by Vanity Fair, the former "Dancing with the Stars" contestant is seen wearing sexy one-piece bathing suits while frolicking in the water and lounging poolside. In some shots, the "bathing beauty's" hair is left down in gorgeous retro waves, while in others, it's piled up into a messy updo. Red lips and cat eyes complete the Marilyn Monroe-inspired look.
And modelling isn't the only project on the blond beauty's radar -- Charlotte is set to star in "Joe Dirt 2: Beautiful Loser" this July.
