I don’t think CNR was fooling anyone when he was on TattleTales with 2 different women.  
While the premise of the show focused on romantic couples, it wasn’t always so, and it is very possible for a gay man to be good friends with a gay woman.  It’s also possible they would know entertaining things about one another.  They were certainly bearding for each other also, but for me, it doesn’t diminish the entertainment value.
