Debra Messing shared a story about the first time she met and worked with Entourage star Jeremy Piven, which was on the set of Will & Grace.

During an appearance on Watch What Happens Live this week, host Andy Cohen asked Messing about her rumored feud with Bobby Cannavale, who played Will's (Eric McCormack) love interest.

Messing denied it but instead said she “wasn’t a fan” of Piven when he played a guest star who propositioned her for a threesome with his girlfriend.

“You know, I had to kiss a lot of boys on that show," she told Cohen, Us Weekly reports. "And we were rehearsing, and the very first day of rehearsal, he shoved his tongue all the way down to my heart."

She also talked about his cockiness on set, saying, "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."

As for Messing’s favorite person to work with on the beloved show, she said it would have to be her on-screen husband Harry Connick, Jr.
