ANDY RODDICK and MARIA SHARAPOVA

The couple have been secretly dating for over a year and recently went public with their relationship at the Zinc Lounge in Manhattan Beach, California.

A source tells American publication Us Weekly, the pair were "beside each other all night."

A friend of Roddick's tells the magazine the couple have kept their relationship quiet because "she was too young."

Roddick is 23 and Sharapova turned 19 on April 19 (06).
