Tennis aces Maria Sharapova and Andy Roddick have reportedly started a love match after falling for each other at the Australian Open.

Russian teenager Sharapova and the American hunk have been spotted relaxing in between games together.

The pair sparked romance rumours when Roddick turned up unannounced at the New York launch of Sharapova's new fragrance line, but back then both insisted they were just friends.

Sharapova was romantically linked to MAROON 5 singer Adam Levine last year (05), while Roddick most recently dated actress/singer Mandy Moore.
