“He’s been doting on Amal’s every need and talking to her belly. He’s also having a blast coming up with baby names,” the insider tells In Touch. “The name Nicholas — after his dad, Nick Clooney — is a shoo-in for his son. As far as girl names, he’s leaving that up to Amal.”

As In Touch previously revealed, he’s thrilled to become a first-time dad at age 55. They’ve already geared up for baby in a big way — as they’ve created a “baby wing” complete with a nursery, a baby spa, a children’s library, and a mini swimming pool. He’s even considering some of his famous friends for godfather — with his pal Richard Kind, production partner Grant Heslov, and Casamigos business partner Rande Gerber all being named as contenders.

They’re especially excited after the struggle they went through to conceive before turning to IVF.

“They had been trying for a baby all summer and it just wasn’t happening, so they sought the help of a fertility doctor and started in vitro fertilization,” the source explains. “George has never had trouble doing anything in his life. Plus, Amal is afraid of needles, so her biggest fear was getting the hormone injections.”

But, it’ll all be worth it when they have little Nicholas — and his sister — in their arms.

“They can’t believe in just a few months, they’re going to have two babies,” the source gushes. “They’re having so much fun looking at all the latest baby gadgets and getting everything ready for the twins. They’re going to be such amazing parents.”
