Well, that didn't take long! While we usually have to wait all of nine months (or longer, in some cases!) to learn a celebrity baby's gender, we now know even more about two Hollywood babies the world can't wait to meet!

Just days after George and Amal Clooney announced that they're expecting twins, George's mother divulged the sex of the babies. "It will be one of each!" Nina Clooney, told Radar Online. "Yes, a boy and a girl. That's what I've been told. How marvelous! My husband and I are extremely excited."

But seems like we'll have to wait a bit to find out what the celebrated couple is going to call their little ones. "I haven't been told their names," Nina explained. "That is George and Amal's department."

An insider tells People that Amal's parents are similarly psyched. Of Amal's dad Ramzi, a friend close to the family notes, “He isn’t saying much, but I’ve never seen him happier. He’s very pleased it will be a boy and a girl."

People also reports that the parents-to-be "quietly let everybody in both families" know about their exciting news over the holidays, while spending time at their English estate. Another insider mused to the siteabout how the famous pair will be as parents. “Amal will be a fantastic mother because she’s mature and has waited for this,” the source says. “They both wanted children and twins is a double blessing.”

Such a blessing for Amal and George and all of their loved ones. We're as excited as the power couple's loved ones. The world truly can't wait to meet these power babies!
