Smitten Spurs soccer star Robbie Keane, dating Miss Ireland finalist Claudine Palmer for more than two years now, pulled out all the stops to flirt with Girls Aloud singer Nadine Coyle at London’s hot spot Pangaea last weekend. “Robbie Keane and Rio had a table right next to Nadine and Kimberley Walsh,” a source told The Sunday Mirror. “He was following her around like a lost puppy. He was whispering into her ear all night. She looked gorgeous.” But despite his flirting, Nadine left with band mate Kimberley and her pals.
