Countdown star Rachel Riley has teamed up with dating website eHarmony to star in its Odds Of Love campaign, discussing the mathematical odds of finding a perfect match and explaining how making simple changes to their daily routines can improve people's odds of finding a partner.

Riley commented 'I'm delighted to be working with eHarmony to help singles increase their odds of finding love. When it comes down to it, love really is a numbers game. Obviously, the more people you make the effort to meet the higher your chances of romantic success. But, as our data suggests, the odds of love can drastically diminish when we get too prescriptive about age, location, looks, and even pet preferences!'.
