Sheen and his wife, Brooke Mueller, are expecting twins, reports People.
According to Mueller’s mother, Moira Fiore, twins are on the way. "Brooke and Charlie are expecting twins, and they are so excited," said Fiore.
The woman added that the happy parents-to-be think that the babies are twins boys, but they aren’t sure.
"Brooke has had all day morning sickness but is coming to the end of the first trimester so she hopefully will feel better soon. It has been rough for her," revealed the future grandmother.
The babies are expected to be born in April 2009.
