Since George Clooney and Amal Alamuddin became a couple last fall, it has been anything but business as usual for the 52-year-old actor. The worldly, beautiful British barrister, 36, has changed his game.

“He's in love with her body and her mind,” says a friend, noting the pair talk world politics and fine wine.

Now that he’s met someone who engages him intellectually, marriage is finally a possibility for the longtime bachelor. Here are four signs he's changed his ways!

Not Flaunting His Love

While exes like Stacy Keibler joined him at red-carpet events, George missed this year's Oscar ceremony. "He flew to London to spend time with Amal, though Gravity was nominated for several awards," says a pal.

Meeting the Parents

Most girlfriends didn't get to meet his folks, Nick Clooney and Nina Warren, but Amal was introduced to them at the White House screening of The Monuments Men in February. "They were blown away by her," says a friend.

Sharing Expenses

"The first sign George was smitten was when Amal insisted on picking up a check," says a friend about the lawyer. "She doesn't need George for his money or connections."

Putting Her First

With her busy career, Amal can't drop everything at a moment's notice for George. When they went on safari in Tanzania, "That was a planned trip because they both have busy schedules and needed to make time for such an adventure," reveals a friend.
