Charlie Sheen's oldest daughter Cassandra Estevez is expecting a baby, which means that before the end of the year the actor will become a grandfather.

It was Sheen's ex, Denise Richards who broke the news to the world on Twitter, congratulating the actor on the new member of his family.

Sheen, who is set to appear on the "Late Show with David Letterman" on Tuesday night, joked about his newest role during the interview.

“Me as a grandfather, Dave...I don't know. It's like the world's going to crack in half," Sheen said. "It's fabulous. It's just not a title I'm ready to adopt."
