Los Angeles, Mar 29 (IANS): Actor-filmmaker George Clooney, also a first-time father-to-be, says that he is happier than before.

During an interview with eonline.com, he spoke about his wife Amal Clooney and their babies.

"Can you believe it?! Yeah, (I'm) even happier (than before)," he gushed.

"I didn't know that we'd have kids. I was very happy that we were going to get married and then (a pregnancy) seemed like the next step."

Asked if he's busy baby-proofing their home or practising how to change diapers, George said: "Hang on for a minute. I played a paediatrician on 'ER' (medical drama)."

George continued: "So I know how to work on extra children... If there's any accidents I'm there. I'm the guy."

They are yet to name their twins.

Explaining their reluctance to do so before meeting them, he teased: "Because I've had friends pick out names around their parents and then it becomes... whatever name you pick they're like, ‘Oh, I don't like that. That guy's a prime minister... Can't name her Susan. You remember your Aunt Susan?'"
