LONDON: Hollywood actress Reese Witherspoon was left red-faced after making a speech in front of British politicians — when UK Prime Minister Gordon Brown mistook her for Renee Zellweger.

The Legally Blonde star stood up in front of Members of Parliament at London’s House of Commons on December 2 to talk about domestic violence issues as part of her role as honourary chairwoman of the Avon Foundation.

After her speech, the British leader addressed the house to thank Witherspoon for her efforts - but he got her mixed up with another blonde Hollywood star. Brown told the house, “I’m very grateful that Renee Witherspoon is leading this campaign. She spoke movingly at the funeral of Anthony Minghella and I welcome her to the house today.”
