Renee Zellweger has remained coy over reports she's dating Sir Paul McCartney.

The pair were widely reported to have been on a date together in August, although the ex-Beatle has been more recently being linked to another actress, Rosanna Arquette.

However, Zellweger was said to have "giggled and blushed" when asked at the London premiere of her new film 'Bee Movie' whether she was seeing Sir Paul.

Although she refused to answer the question directly, she did say, "I have not seen him since I have been in London."
