It may be on again between George Clooney and Monika Jakisic.
The actor, who we first connected to the Croation model in 2007, reportedly slept over with Jakisic at his Los Angeles mansion on September 25.
We doubt much sleeping was involved, though, if you know what we mean!
"They have an incredible connection," an insider tells Us Weekly of Clooney and Jakisic.
The sexual tension had been building for a while. Back in May, the London-based stunner, 33 -- known as the "Croatian Sensation" -- and the Gravity actor unabashedly flirted at London nightclub Loulou's.
The pair allegedly "held hands and danced" back in May inside London nightclub Loulou's, though little else went down at the time because Clooney was still dating Stacy Keibler.
