Cassandra Estevez, 28, and Casey Huffman welcomed their daughter, Luna, on Wednesday, July 17. Sheen, 47, said:
It's impossibly a most wondrous day. My bucket list is a thimble!More shocking, perhaps, is that Martin Sheen is now a great-grandfather. Martin Sheen has eight other grandchildren (aside from Cassandra), but this is his first great-grandchild.
Sheen had Estevez with his high school girlfriend, Paula Profit, when he was 19. Sheen is also fathered daughters Sam, 9, and Lola, 7, with second wife Denise Richards, and 4-year-old twin sons, Bob and Max, with third wife Brooke Mueller. He had no children with first wife, Donna Peele.
Sheen confirmed his daughter was expecting her first child during an appearance on "The Late Show With David Letterman" in January (embedded). He also admitted being nervous about it.
Me as a grandfather, Dave ... I don't know. It's like the world's going to crack in half. It's fabulous. It's just not a title I'm ready to adopt.Estevez and Huffman were wed in 2010, with Sheen -- the proud father -- walking his daughter down the aisle.
