British PM Gordon Brown's Hollywood Mix-up

When it comes to Hollywood stars, Britain's prime minister can't tell a Reese from a Renee.

Gordon Brown was asked in the House of Commons to congratulate Reese Witherspoon, who visited Parliament Wednesday in her role as a campaigner against domestic violence.

Brown replied that he was "grateful that Renee Witherspoon is leading this campaign." He said the actress had spoken movingly at the funeral of director Anthony Minghella.

Renee Zellweger starred in Minghella's "Cold Mountain" and spoke at his memorial service last year.

Witherspoon is the Academy award-winning star of "Walk the Line" and "Legally Blonde."
