Keenan Ivory Wayans' Ex To Join Hollywood Exes Cast

Sources tell us, Daphne Wayans -- who was married to Keenan from 2001 to 2004 and has 5 children with him -- will join the cast for the second season of the VH1 show ... just as soon as they get picked up by the network.

Wayans will be in good company ... joining the exes of Prince, R. Kelly, Will Smith, Eddie Murphy and Jose Canseco as they try to come out of their husbands' shadows and into their own.

Ya know ... by using their famous last names.
