Singer Beyoncé Knowles and her rapper boyfriend Jay-Z have started planning their wedding, which is to take place in the Caribbean some time next summer.

The wedding is reportedly going to be a very private affair, with all the details being kept private from press scrutiny. A friend of the couple commented: "Both Beyoncé and Jay are determined to avoid turning the day into a media circus. So only they and their parents will know the full details until the very last minute."

Beyoncé and Jay-Z have dated for three years before deciding to exchange rings.
