Actor George Clooney, 54, said marriage has completely changed his life. The “Tomorrowland” star revealed he “couldn’t be happier” with his relationship with wife and attorney Amal Alamuddin.

“That’s right, I’m a married man now,” Clooney said on “Good Morning America” on Thursday. “Everything’s different now. Actually it is. I was going to make a joke but it is actually.”

“I couldn’t be happier,” the actor continued. “We’re having a really fun time. We’re working on fixing up a house in England that we’ll be spending a lot of time in just outside of London. And we’ve been sort of traveling the world. We’re on our way to Shanghai.”

Clooney added that the couple tries to spend as much time together as possible, a difficult task since his wife “actually has a day job.”

The former “ER” star also raved about his wife to Entertainment Tonight on May 7. "She's an amazing human being," he said. "And she's caring. And she also happens to be one of the smartest people I've ever met. And she's got a great sense of humor. There's a number of reasons why."

The actor proposed to Alamuddin in late April after seven months of dating, and the couple obtained a marriage license from the Royal Borough of Kensington and Chelsea in London in August. The two were married in Italy on Sept. 27, 2014, in a ceremony that reportedly cost $13 million and included guests Matt Damon, Julia Roberts, Brad Pitt and Angelina Jolie. The event lasted three days and Clooney shipped in 100 cases of his own brand of tequila, Casamigos.

Clooney had been married before -- to actress Talia Balsam, from 1989 to 1993. Following the divorce, he proclaimed he’d be a lifelong bachelor and dated a number of Hollywood celebrities -- from Stacy Keibler to Sarah Larson.
