Rihanna carried a bouquet of flowers while her Middle Eastern man grinned ear to ear on their romantic Ibiza getaway this week.
RiRi, who has long been pop's most eligible bachelorette, donned a black and white striped baggy pantsuit with pointed flats as she held on to a black bomber jacket for later.
Jameel is the first flame linked to Rihanna since her last relationship.
Hassan's family ranked No. 12 in Forbes Middle East's list of the world's richest Arabs with a net worth of $1.5B last year.
They also said to own a soccer league in Saudi Arabia, called the Jameel league.
