Danica McKellar at 2014 American Music Awards in Los Angeles. Danica McKellar showed off her legs in a delicate green lace dress at the American Music Awards on Sunday night. Her pins were just barely visible through the mesh panel along the skirt and she gave just a small peep of cleavage. So tasteful! And yet still super hot! The 39-year-old's half-up/half-down hairdo was a bit "prom," but she was still an overall gorgeous sight!
