George sure knows how to pick 'em! George Clooney's new flame -- "Croatian Sensation" Monika Jakisic -- is a stunner in a cleavage-baring lingerie shot taken by LA-based photographer Marcel Indik.

In the lingerie photo, Clooney's once ex Jakisic strips down to a matching black bra and undies while posing seductively for the camera. The 33-year-old also shows off her toned physique and rock hard legs with thigh-high leather boots.

Us Weekly exclusively revealed on Oct. 2 that Clooney, 52, and the London-based model had a sleepover at his L.A. mansion on Sept. 25.

"They spent hours talking, and have an incredible connection," an insider told Us. "He's been calling and texting her ever since."

Clooney and Jakisic have had an off-and-on fling since 2004, and first reconnected at London nightclub Loulou's with some heavy flirting in May. Though the two met up when Clooney was technically still dating Stacy Keiber, the Gravity actor would split with the WWE star in July after two years of dating.
