Picking favorites isn't easy -- and Nick Cannon is about to be in a very uncomfortable situation regarding this difficult action. Making matters more awkward: It has to do with the mother of his children.
"Great father, by the way" Rip begins, as Nick expresses his gratitude. It's always best to serve up a lovely comment -- before going straight for the jugular.
"Question is simple: Who is your favorite baby mama?" Rip inquires (ahem, Mariah Carey and Brittany Bell).
How does Nick react -- and does he offer up a reply (or PTF)? Watch the cringe-worthy clip below, and don't miss the entire Wild 'N Out episode on Thursday at 11/10c!
