Did Clooney Father Stacy's Little Girl?

George & Stacy stayed friends after their romance fizzled

- 

George and Amal Clooney’s marriage is hanging by a thread over bombshell claims that he fathered a secret love child, sources told The National ENQUIRER in a shocking exclusive.

The Hollywood superstar, 58, is suspected of impregnating ex-girlfriend Stacy Keibler around the same time he started dating Amal, 41, in 2013, according to insiders.

Former WWE wrestler Stacy, 39, married businessman Jared Pobre in March 2014 and gave birth to daughter Ava the following August.

But sources have been quick to point out the cutie bears an uncanny resemblance to George’s twin son, two-year-old Alexander!

Tensions between the Clooneys — who wed in September 2014 — reportedly reached a boiling point after an anonymous letter arrived at their villa in Lake Como, Italy, according to sources.

“The talk is this letter stated quite clearly George is the daddy of Stacy’s daughter and he needs to take a DNA test to clear the matter up once and for all,” divulged an insider.
