Charlie Sheen: Odds Are It's a Boy

What makes the newlyweds so sure? Well, Charlie's three other children (Sam, 4, and Lola, 3, with ex-wife Denise Richards, and Cassandra, 23, with ex-girlfriend Paula Profitt) are all girls. And unless, as he said, he's "batting 100 percent," the couple thinks they'll be decorating the nursery with baseballs rather than Barbie dolls.
"Odds are it's a boy, but we'll be happy with either sex," Brooke told PEOPLE Friday at the opening of Yellowtail Sushi Restaurant in Las Vegas.
Sheen echoed his wife's statement, saying, "We're just hoping for a healthy baby, but there's a chance (for a boy) – odds are positive."
Rumors had been swirling before the Sheens confirmed their pregnancy earlier in the week, and the couple was disappointed in the way the news broke. "It would have been nice to do it on our terms," said Sheen. Added Brooke: "We were hoping to be a little further along before news got out."
Earlier in the evening, the expectant couple – along with Sam and Lola – joined Palms Casino Resort owner George Maloof and KISS singer-guitarist Paul Stanley at N9NE steakhouse to celebrate Charlie's 43rd birthday (which is on Sept. 3) a few days early.
