While George Clooney was linked to Amal Alamuddin on Tuesday, a new report claims he is not dating the British attorney but instead, has rekindled his romance with model Monika Jakisic.

"Monika and George are dating," the insider told Us Weekly of the pair that first hooked up in 2004.

The source said that although the pair isn't dating exclusivlely, the model, dubbed the "Croatian Sensation" has been spending quality time with him since his split from Stacey Keibler.

"She's not his official 'girlfriend' yet, but they've become very close," the source said. "She has been seeing George almost every night."

InTouch Weekly reported in May that Clooney and Jakisic displayed PDA in a London nightclub around the time he was still dating Keibler. The model is based in London, where the Oscar-winning actor has been shooting the upcoming movie The Monuments Men.

"They seemed to be having a great old time together," an eyewitness told the magazine. "He didn't seem to care who saw them. He was being openly affectionate... He looked very happy - they were smitten with each other."

After Clooney and Keibler, who dated for two years, announced their split in July, Us Weekly reported that Jakisic spent the night with the two-time Oscar winner on Sept. 25. A source told the magazine they rekindled their romance because they have "an incredible connection."

"They danced and held hands" at the London nightclub Loulou's back in May, added the insider. "He's been calling and texting her ever since."

However, Clooney denied the claim and told Mail Online exclusively at the time: "The story is made up. I wasn't holding anybody's hand. Stop trying to sell magazines by creating scandal that isn't there."
