Debra Messing is not afraid to kiss and tell. The actress made an appearance on "Watch What Happens Live" where she dished on her favorite and least favorite kissers during her "Will & Grace" years. The 46-year-old was quick to single out Jeremy Piven as the worst kisser in her eight years on the show.
"You know, I had to kiss a lot of boys on that show," said Messing. "And we were rehearsing, and the very first day of rehearsal, he shoved his tongue all the way down to my heart. I was just like, 'Whoa!' He goes, 'Yeah, yeah,'" she told "Watch What Happens Live" host Andy Cohen. "He was like, 'That's it, I'm in.' I was like, 'You know, this is comedy. We don't really go that deep.' And every time he went for it."
Piven made an appearance on a season three episode, playing one of Grace's ex-boyfriends. Piven's character asked Grace to join him in a threesome with his current girlfriend and she agrees to it, according to Us Weekly.
Messing also revealed her favorite kisser on the show was Harry Connick Jr., whose character is Grace's eventual husband, Leo, according to the Daily Mail.
