Why She Has Our Vote: No doubt Mariah Carey (pictured at the Oscars on March 7, 2010) has been busy lately, with a new album in the works and a potential mentoring role on Fox'sThe X Factor -- not to mention caring for her 4-month-old twins, Monroe and Moroccan, with husband Nick Cannon! But Carey recently tweeted that she's hired a personal trainer to help her get back in pre-baby shape. Why not nix the trainer and salsa-dance the pounds away? DWTS has a long history of helping new moms lose the baby weight, from Tia Carrere to Kendra Wilkinson. Plus, DWTS can be time consuming, so hopefully it would prevent Mariah from doing any more seriously weird appearances on HSN.
