The mystery man pictured slobbering all over Rihanna in a Spanish swimming pool has been identified as Saudi businessman Hassan Jameel, who is believed to be one of the wealthiest men in the world.

Hassan is the deputy president and vice chairman of the family-run business Abdul Latif Jameel, one of the world's most successful companies, and key investors in Toyota. According to sources, the pair have been discreetly dating for several months, despite the grainy paparazzi pictures being the first public confirmation that Rihanna was even in a relationship.
