The mystery man Rihanna was pictured making out with while holidaying in Spain is Saudi billionaire Hassan Jameel.

Jameel's family own the distribution rights to Toyota in Saudi Arabia and their fortune is estimated to be worth around $1.5 billion.

While Rihanna has pots of money of her own, sexy Saudi Hassan is a great catch for any single girl. He is after all tipped to inherit all that lovely lolly one day.

Pictures of the pair getting hot and heavy in the swimming pool of a Spanish villa has been making the rounds on social media.

The singer and the Saudi hottie clearly had "Love on the Brain" and can be seen sipping champagne in between their cuddle sessions.

While Riri hasn't been linked with anyone in any serious way since her much talked about break-up with bad boy Chris Brown, reactions  on social media were something else!!
