7 of 13

MELISSA MOLINARO

Age: 29
Occupation: Model and singer
Why she should dance: The Kim Kardashian look-alike has moves – remember her controversial "Super C-U-T-E" Old Navy commercial? – but can she last longer on the show than Kardashian, who left early on season 8? Odds are good: Molinaro told PEOPLE she's been dancing since she was 3 years old.
