The warlock is a grandfather, tiger blood and all. Actor Charlie Sheen, 47, became a grandfather Wednesday when daughter Cassandra Estevez and her husband, Casey Huffman, welcomed their first child, a daughter named Luna.
"It's impossibly a most wondrous day," Sheen told TMZ. "My bucket list is a thimble!"
Sheen also tweeted his congratulations to the new parents, and wrote, "hey Luna, welcome to my planet!"
Cassandra Estevez, 28, was born to Sheen and his high school girlfriend Paula Speert back in 1984, when Sheen was just 19.
Sheen has four other children. Daughters Sam, 9, and Lola, 7, were born to Sheen and actress Denise Richards, and twins Bob and Max were born to Sheen and then-wife Brooke Mueller. Bob and Max are just four years older than their new niece.
