CHARLIE SHEEN has officially become a “grampa” to his newly-pregnant daughter CASSANDRA.

It’s true!

At age 47, Charlie Sheen sure doesn’t look like he’ll be quitting his bachelor living anytime soon—he’s currently dating another porn star “goddess,” Georgia Jones—but someone close to the “Scary Movie” actor sure has moved on to the next stage of her life… his eldest kid, Cassandra Estevez, who is currently pregnant with her first child.

And you know what that means… the crazy warlock is now a grandfather!

But the first-time poppy didn’t seem all that excited about being… old. He joked during an appearance on David Letterman‘s “Late Show” last Monday:

“Me as a grandfather, Dave… I don’t know. It’s like the world’s going to crack in half.”

He quickly added:

“It’s fabulous. It’s just not a title I’m ready to adopt.”

Rightfully so… He certainly isn’t the world’s best role model, except for his charitable side.

His ex-wife Denise Richards, however, was simply thrilled about the news… or the idea of Sheen becoming a granddad.

She tweeted on Tuesday:

“I guess some of you have heard… @CharlieSheen is going to be a Grampa…yes GRAMPA! his beautiful daughter Cassandra is gonna be a mama.”

See what else he had to say about his new “title,” his world-famous meltdowns and how he dissed “Two and a Half Men” again:
