Charlie Sheen is Going To Be A Grandfather

Charlie Sheen is going to be a grandfather! Sheen's oldest daughter, Cassandra Estevez, 38, and her husband are expecting their first baby, and he or she will be the first grandchild for the former Two and a Half Men star.

It is a little strange to think of the actor as 'Grandpa Charlie,' - even to Sheen himself, who shared the news with David Letterman.

'Me as a grandfather, Dave... I don't know. It's like the world's going to crack in half,' he joked.

But Sheen quickly added: 'It's fabulous. It's just not a title I'm ready to adopt.'

Sheen, who became a father at 19 when his high school girlfriend Paula Profit gave birth to Cassandra, is also dad to daughters Sam, eight, and Lola, seven, with his second wife Denise Richards, and three-year-old twins, Bob and Max, with third wife Brooke Mueller.
