NBC has fired back at Doug Kepanis, a divorce lawyer featured on Bravo’s “Millionaire Matchmaker,” after he sounded off to Page Six about his horrible experience with matchmaker Patti Stanger. Kepanis claimed he was dropped as a legal expert from TruTV because he was made to appear sexist on the reality show. Sources now say Kepanis has received a cease-and-desist letter from Bravo parent NBC preventing him from talking about the show. When we called Kepanis to confirm, the previously loose-lipped lawyer said, “No comment.” A Bravo rep didn’t get back to us.
