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.
But he split with her in July and has been "calling and texting" Jakisic ever since, this source claims.
Keibler has also moved on, recently sharing a photo of herself and new boyfriend Jared Pobre drinking wine in Paris. There are no hard feelings between the exes.
"They are both working and haven't seen each other," a source says of the breakup, giving a clear reason for why it didn't work out: "You can't have a relationship with someone that you don't see."
