"Grandfather," Sheen happily replied. The actor explained that oldest daughter Cassandra Estevez, 28, is pregnant with her first child with husband Casey Huffman.
Sheen, who suffered a very public meltdown in 2011, joked that he'd definitely be a good grandfather "because you can leave the kid!"
Though Estevez's mother is Sheen's high school girlfriend Paula Profit, the actor's second ex-wife shared in Sheen's joy. "I guess some of you have heard... Charlie Sheen is going to be a Grampa... yes GRAMPA! His beautiful daughter Cassandra is gonna be a mama," Denise Richards tweeted.
While Sheen said the news is "fabulous," he admitted that he's not quite "ready to adopt" the title just yet. Maybe he can take a cue from Real Housewives' NeNe Leakes and be the world's first glamfather?
