Well, this is sure to make you feel, like, really old.
Backstreet Boy Brian Littrell has a 13-year-old son.
If you are trying to do the math -- Baylee Littrell was born on November 26, 2002, which for context, is about a year after the band released their greatest hits album "The Hits -- Chapter One."
For any die-hard fans of the BSB, young Baylee's existence probably isn't surprising, since he has performed onstage alongside his dad and the group from time to time -- and even opened for the boy band last year.
But if you tend to view the Backstreet Boys as pure nostalgia, then we're sorry for making you feel ancient.
Anyway, talent apparently runs in the family as Baylee made his Broadway debut on Thursday night, playing two characters in "Disaster! A Musical," which parodies 1970s disaster movies.
The teen, who has never performed professionally before, told the Associated Press, "When I think about it, I accomplished something that not a lot of people get to achieve in their life. I'm still a little shocked. It still hasn't come out of my mind yet."
Oh, and if you're wondering about the rest of the band: AJ McLean has a 3-year-old daughter, Howie Dorough has two sons ages 6 and 3, Kevin Richardson has two sons ages 9 and 2, and Nick Carter and his wife are expecting a son later this year. Whew.
