Later this year Nicole Richie will marry Good Charlotte rocker Joel Madden. However the wedding plans are being kept a secret from everyone, including Nicole Richie’s father, Lionel Richie.

Lionel Richie is also very famous and Nicole Richie believes that her father is incapable of keeping a secret. He admitted this inability himself to Britain’s The Sun. Lionel Richie said, , “I honestly don’t know (when the wedding will be). They won’t tell me because they know I will tell everyone. I can’t keep a secret.”

Despite his lack of knowledge concerning the wedding details, he has made his daughter promise that she will not make him do anything cheesy, including singing at the ceremony.
