Still going strong! Though he was photographed out on the town with a "mystery woman" late last week, George Clooney is still quietly seeing "Croatian Sensation" Monika Jakisic, a source tells Us Weekly.
"Monika and George are dating," the insider says of the pair, who first hooked up back in 2004 and then rekindled their fling in September, after Clooney's July split from Stacy Keibler. "She's not his official 'girlfriend' yet, but they've become very close. She has been seeing George almost every night."
Jakisic -- a 33-year-old model based in London, where the Oscar-winning actor has been shooting the upcoming movie The Monuments Men -- has "an incredible connection" with Clooney, another insider previously told Us. "They danced and held hands" at London nightclub Loulou's back in May, the source added. "He's been calling and texting her ever since."
Last week, rumors swirled that Clooney had moved on when he was spotted getting into a car with a different woman -- identified by E! News as barrister Amal Alamuddin -- after grabbing dinner at Berners Tavern in London. But sources tell Us the evening was "non-romantic," and that Alamuddin is "just a friend."
Jakisic, on the other hand, is definitely more than a friend. During a recent date at the Connaught, a hotel in London, the two stayed up chatting well past midnight. "George was making Monika laugh and holding her hand," an eyewitness tells Us. "It looked like he was having a great time."
