Charlie Sheen has announced fabulous news - that he is going to become a grandfather. The 47-year-old actor revealed on David Letterman that his 28-year-old daughter Cassandra Estevez and her husband were expecting their first child, the Daily Mail reported. Me as a grandfather, Dave... I don’t know. It’s like the world’s going to crack in half, he joked.

But he quickly added saying, It’s fabulous. It’s just not a title I’m ready to adopt.

Cassandra is Sheen’s daughter with his high school girlfriend Paula Profit, and was born when he was 19.

He gave her away in 2010 when she married her high school boyfriend Casey Huffman.
