Photos of the Umbrella singer, 29, enjoying a steamy make-out session in a hot tub at a private luxury villa in Spain emerged online on Tuesday (27Jun17).
The man who was pictured passionately kissing Rihanna as they frolicked in the water has now been named by editors at British newspaper The Sun as Hassan, the heir to a Saudi business empire.
"This relationship is the real deal," a source told The Sun. "Rihanna has told friends she's in love with him and seems completely smitten. They've been spending a lot of time together away from prying eyes and are really serious. They're really enjoying each others' company."
Hassan is the deputy president and vice chairman of his family business Abdul Latif Jameel, one of world's biggest companies. His net worth has reportedly been estimated at $1.5 billion (£1.2 billion).
Although the firm's value is unknown as it is not publicly listed on the stock market, Hassan's family have extensive interests in finance, real estate, the motor and technology industries, and they own the rights to sell Toyota cars in Saudi Arabia.
Hassan is thought to be a close pal of Naomi Campbell and the pair were seen together watching Stevie Wonder perform at last year's (16) British Summer Time Festival in London's Hyde Park.
Rihanna's new romance is her first known relationship since she reportedly called it quits with Canadian rapper Drake last year (16). She has also been linked to stars including Leonardo DiCaprio and rapper Travis Scott.
Her other exes include baseball player Matt Kemp and R&B singer Chris Brown, who assaulted her before the 2009 Grammy Awards.
