Billy Bob Thornton refused to celebrate his 70th birthday over the summer

Thornton told RollIing Stone magazine: "Connie asked me what I wanted and I said: 'Nothing, absolutely nothing. As a matter of fact, don't mention it to anybody'.

"We really just hung out here at the house, just me and Connie and the kids, and had a nice time, and they got me a vegan cake, which - I can't eat wheat or dairy, so that was awesome. Anytime a guy like me could have cake, it's a great day."

Thornton went on to reveal he's very happy with Connie - his sixth wife who he wed in 2014 - and they have built a loving and stable life together.

The actor added: "Connie and I have been together 23 years and married for 12. Our daughter is 20. So, I found the right spot to be.

"The other times I got married were just like, you had a little too much to drink one night and somebody said: 'We should get married.'

"You go: 'Yeah, OK.' I always tell people, at least I was trying."

Thornton previously admitted he doesn't consider himself to be part of Hollywood because he avoids the party scene and prefers to spend time at home with his loved ones.

He told People: "I don't talk about politics and stuff with people. I just kind of stay out of it all. I'm not really much of a part of Hollywood, as you say.

"I'm at home with the family, or I'm in a recording studio or on the road or making this.

"Those are the things I do, and I just kind of mind my own business."

His latest project is playing Tommy Norris - a landman for an oil company - in the Paramount series Landman, and he's enjoyed playing the character more than he initially imagined.

The actor added: "It's almost like a few characters I've played boiled into one. He's like the guy from Goliath, Bad Santa, it's like he doesn't suffer fools, but he also has some fun every now and then. I'm just basically playing who I would be if I were a landman."
