The entrepreneur is already the father of three children -- Donald Jr., Ivanka and Eric -- with first wife Ivana and daughter Tiffany with second wife Marla Maples.

The fourth season of "The Apprentice" premiered on Thursday, Sept. 22, just a day after the debut of "The Apprentice: Martha Stewart." His wife has appeared on numerous runways and fashion magazine covers worldwide.
