The 29-year-old was first spotted with her new love, whose family have dealership rights to Toyota cars, earlier this year as they got hot-and-heavy in a pool in Spain .
Since that sighting, they have remained low-key about their love.
However, The Sun report the handsome businessman was married before meeting the star as sources revealed he tied the knot with art expert Lina Lazaar at Paris Opera House in 2012 – yet both parties have now happily moved on.
Hassan is the deputy president and vice chairman of family business Abdul Latif Jameel – one of the biggest companies in the world. Rihanna is not the first of his famed romances as he was previously linked to Naomi Campbell.
Sources tell The Sun: ‘
Hassan is an intensely private individual. His marriage was over before he met Rihanna, after getting a divorce from Lina, but it will still come as a shock to her millions of fans. Lina has also moved on with a new partner.’
