Sir Paul McCartney has denied reports he is dating actress Renee Zellweger, insisting they simply share the same friends. The former Beatle was rumoured to be romancing the Bridget Jones's Diary star after the couple was recently photographed dining together in New York. And on Tuesday (04Sep07), Zellweger further fuelled reports of a relationship by declaring she has a "crush" on the rocker. But MCCartney - who is currently embroiled in a divorce battle with his estranged wife Heather Mills - has dismissed the media speculation. He says, "We're not dating. We're in the same group of friends and that's it."
