Michael Douglas Is 'Ecstatic' About Birth of First Grandchild Lua: 'We're So Happy'

Michael Douglas is over the moon with his new granddaughter — and even reveals her name.

The actor, 73, tells PEOPLE exclusively that he and his family are “all ecstatic about baby Lua!”

This is the actor’s first grandchild by oldest child Cameron Douglas, whom he shares with his first wife Diandra Luker. Michael also has two children with his second wife Catherine Zeta-Jones: son Dylan, 17, and daughter Carys, 14.

“Dylan and Carys love being an aunt and uncle and we’re so happy to be her Bubba and Zeze,” Douglas says, speaking of the names the baby will know him and his wife as.
