GEORGE CLOONEY swears he’ll never tie the knot again, but GF STACY KEIBLER apparently has other plans – and her scheme seems to be working !!

As the lovebirds approach their second dating anniversary, insiders say Stacy is playing the Oscar winner’s heart like a fiddle.

“At first, I wouldn’t have given them two months, much less two years,” a family friend told The ENQUIRER. “While Stacy is certainly gorgeous, she’s this D-List celebrity on the arm of one of the most powerful men in Hollywood.

“BUT GEORGE ONLY SEEMS MORE drawn to her as time goes by.”

Another source notes that leggy Stacy – a former pro wrestler – has been “unbeliev­ably savvy” in navigating her relationship with George.

The friend continued: “She studied him and learned to keep her distance when she needs to. She knows that other women forced themselves too quickly into his life and he hated that.

“She goes off and does her own thing whenever George is spending time with his pals or is deep into a film project – she doesn’t even call him. But eventually, he starts missing her, and he’s the one who calls. She lets George come to her.”

George, 51, divorced “Homeland” actress Talia Balsam in 1993 after four years of marriage. Although he’s dated some of the most beautiful women in the world since then, he’s publicly affirmed many times that there’ll never be another Mrs. Clooney.

Still, the family friend says not to bet against Stacy, 33.

“This is the most comfort­able I’ve ever seen George in a relationship,” the friend added. “I think George may even realize, as he’s getting on in years, his pledge to remain a bachelor is kind of a hollow one.”
