While celebrating 15 years of "Watch What Happens Live," Andy Cohen revealed that one of his "few regrets" was asking Oprah Winfrey a controversial question during her 2013 appearance on the show.

Cohen, now 56, had asked Winfrey if she had ever "taken a dip in the lady pond," to which she responded, "No, no, I have not. Thank you."

"This was a huge moment for me and for the show," Cohen said in an interview with Entertainment Tonight. "I’m such a fan of Oprah." However, Cohen admitted he got caught up in the excitement and asked the inappropriate question despite knowing better.

"It meant so much to me that Oprah Winfrey did the show," Cohen reflected. "Everything was going brilliantly, and then I turned around and asked her if she had ever had sex with a woman. I mean, couldn't I just leave it alone?"


Cohen further shared that Winfrey's close friend Gayle King later told him that the "Color Purple" actress didn't understand what he meant by the term "lady pond." "I thought I explained it pretty well there, but listen, I was so grateful that Oprah did the show and I still am," he said, adding that the episode remains his favorite.

Cohen also reminisced about another favorite "WWHL" guest, Patti LuPone, who has made numerous appearances since the show began in 2009. "Patti LuPone has no F's to give, so she is the perfect clubhouse guest," Cohen gushed.

In a 2017 interview with Cohen, the Broadway star famously took a shot at Madonna, calling the "4 Minutes" singer a "movie killer." "This clip got me in a lot of trouble with Madonna, who called me a 'troublemaking queen' from the stage of her Celebration Tour," Cohen recounted. "She said, 'You need to stop talking crap about me on your show.' Now, the truth is, it wasn’t me talking crap about her. It was people like Patti LuPone—who I also love, by the way."


Reflecting on the show's success, Cohen attributed it to its spontaneity, authenticity, fun, and humor. "The secret to 'Watch What Happens Live,' I think, is me going there and people never knowing what’s gonna happen."

Looking ahead, the father of two said his focus is "all about the kids," keeping the talk show alive, and "keeping the 'Housewives' as fresh as we can."
