The 57-year-old actor only welcomed his son Rafael Thomas into the world three months ago but he's desperate to have another baby with his wife Hilaria, 31, whom he married in 2012, so they can expand their family even more.

Speaking to PEOPLE.com, he said: "I'm dying to have another child with my wife.

"I love my wife more than anything. I love our family, I'm very happy. I've never been happier before in my life."

The former '30 Rock' star also has two-year-old daughter Carmen with Hilaria and Ireland, 19, from his marriage with his ex-wife Kim Basinger and believes the arrival of his new bundle of joy has brought his family closer together.

He explained: "Even my daughter Ireland has been visiting and we see her falling more in love with Carmen every day.

"It's really fun.This is the best time of my life and I owe it all to my wife, truly."

Although they have their hands full with their two young children and their busy careers, the couple haven't let their private time slide and always try to make time for date night.

Hilaria said: "We have some babysitters that are really great. To us, date night actually means that we can talk to each other. When you go to a lot of events, it's really fun and you talk to other people, but you don't talk to each other."
