Actress Renee Zellweger insists there is no romance between her and George Clooney - just a shared love of politics and letter-writing. The pair reportedly dated in 2003 after Zellweger split from fiancé Jim Carrey. But now the Bridget Jones star, 38, reveals her and Clooney, 46, are more than just friends - they are pen pals. She says, "We have a lovely relationship. I write him six-page e-mails about my political rage, and he writes back, and cares too."
