Salma Hayek is one hot mama -- and last week at Cannes, she showed off her smokin' body all over the red carpet. (See more pics from Cannes!)
According to Beauty Undercover -- who spoke with Salma's trainer, Darci Bawdon -- the secret to the 43-year-old, mother of one's slim figure is a mix of pilates and the Paleta Diet.
The diet includes a 10-day cleanse and then an organic meal plan.
