Actress and model Molly Sims was recently interviewed by Health magazine, and dished on what she finds lacking in the celebrity fashion style of tabloid favorites Britney Spears and Heidi Montag.

Spears, she says, is “so pretty,” but needs help choosing fashion trends because she tends to have “too many trends going at once.”

Sims also criticized the celebrity fashion trend of major plastic surgery, singling out Heidi Montag, star of MTV show “The Hills.” Sims told the magazine, “Something is off. You don’t get F-size boobs.”

She also recently appeared at the Home Shopping Network’s 33rd birthday celebration in Las Vegas, along with stars like Susan Lucci, Tori Spelling, and Wolfgang Puck.
