The pair turned heads after not being seen in public together for weeks.
The couple left the restaurant separately choosing not to be pictured together with Rihanna, 29, exiting out the back door at around 2am, DailyMail learnt.
She then sat in her car for half hour before Hassan left out of the front door of the restaurant a 2.35am.
Rihanna wore an all black, spilling her curves into a sweater and a mini-skirt, showcasing her pins.
She wrapped a casual black coat around her and added a pair of this season’s trend sock boots, also in black.
She carried a Dior bag – a brand affiliated with the singer who is the first black woman to front a campaign by the brand.
The Rude Boy singer tied her raven mane tightly back behind her head and wore a fresh face of natural make-up, just a slick of gloss to her lips.
