George Clooney Admits His ‘Don Juan Days’ Are Over as He Juggles Broadway and Family Life

Gorgeous George Clooney is still a girl magnet at age 63, but sources say the Ocean’s Eleven thief admits he’s no longer a balcony-climbing Don Juan and feels pressure when it comes to slipping between the sheets with his stunning younger wife, Amal! The Money Monster star and the 47-year-old humanitarian lawyer are nesting in the Big Apple as he makes his big Broadway debut in the play Good Night, and Good Luck — and sources say that between rehearsals, keeping in shape with workouts, and other business, he’s had little time for late-night canoodling with the mom of his 7-year-old twin muppets, Ella and Alexander.

“George is making every effort to keep up with her energy levels but freely admits he’s not getting any younger, and it’s starting to take a toll,” spills an insider.

“He’s working long hours in New York on his play and doing his part with the kids and hitting the gym most days, too, so by the time he’s had his dinner he’s ready to hit the hay.”

George recently admitted that even with staying in shape and the right diet, aging takes a toll.

“In 30 years, I’m 90. That’s a real number,” he says. “My dad just hit that. And there are some things you’re not doing no matter how many granola bars you eat.”

Sources snitch that his time for kissy-face with Amal has gotten even shorter since the March 12 start of his play’s Broadway previews.

The drama — cowritten by Clooney and Grant Heslov based on their 2005 movie — tells of broadcaster Edward R. Murrow’s battle against Sen. Joseph McCarthy, who ruined untold innocent lives with his “red scare” crusade. It runs through June 8.

Each performance takes an hour and 40 minutes, with no intermission — giving George no break and demanding tremendous energy.

And on top of that, “It’s his first stage role and he’s nervous and pumped at the same time,” says the insider. “The downside of all this is that his sexy time with Amal has taken a back seat, and that’s bumming George out.

“He still looks good and feels perfectly fine, but those legendary Don Juan days of his are sadly drawing to a close!”
