Watch How Quickly Debra Messing Responds When Rach Asks If Her 13-Year-Old Son Is Dating Yet

Debra Messing was warned that her son, Roman, would grow up sooner or later, but she’s always been in denial -- as most parents usually are!

"It’s killing me," she says. "I was told that boys become men, and I was like, 'Oh, but mine’s not!'"

Sure enough, though, the now-14-year-old showed up to his mom’s Hollywood Walk of Fame ceremony in October looking all grown up -- in a suit and everything.

And while the "Will and Grace" star has been forced to come to terms with Roman not being a little boy forever, there’s one thing she’s still adamant about.

When Rach asked if Roman is dating yet, Debra responded IMMEDIATELY with a resounding no. (Seriously, watch the video above to see how quickly she responded!)

According to mom, Roman’s too busy with flag football, hockey and his stand-up comedy class.

Impressive!
