Brooke, 31, and Charlie Sheen, 42, will have their hands full this spring. "Brooke and Charlie are expecting twins, and they are so excited," says Brooke's mom Moira Fiore. "Obviously, I am floating on air." Fiore says the couple "thinks the twins are boys" but 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," Fiore says. "It has been rough for her." Still, "Brooke looks so beautiful. She is just glowing." Sheen, who is already a father to three girls, has expressed interest in having a son. In August, Brooke told PEOPLE she thought they would have a boy. "Odds are it's a boy, but we'll be happy with either sex," she said at the time. The babies are due in April.
