George Clooney

E! News -- George Clooney is a very happy man. Like, very happy.

Not only did his latest movie, Tomorrowland, premiere at Disneyland yesterday, but along for the big event were his wife Amal Clooney and their niece Mia Alamuddin.

The Oscar winner raved about married life.

"It's fun," he told me on the premiere's blue carpet. "It's really fun."

The two were married seven months ago in Italy.

He acknowledges that he was once the butt of many jokes about his long list of girlfriends and his apparent never-ending bachelorhood.

"There were all the jokes and the bits and I get all that stuff, but I couldn't be happier right now," said Clooney, who turned 54 last week. "I wake up in the morning and I think, 'This couldn't be better.'"

Amal, Clooney said, is getting adjusted to all the attention.

"Used to it as much as you can get used to it," he said before pointing to the crowded carpet and saying, "I mean, this gets a little nutty. It's tricky sometimes walking outside of a hotel and having people follow you and stuff.

"It's hard to still practice law," he added with a laugh. "Sometimes it is, but she's handling it really well."

After the screening, the Clooneys and Mia rode the monorail to the park's Tomorrowland area and went on Space Mountain. They were also spotted hanging in the party's VIP area with friends Cindy Crawford and Rande Gerber and their son and daughter.
