Rihanna and her billionaire Saudi beau Hassan Jameel continue to fuel rumors that their relationship is not only going strong but is also pretty serious. 

Last week, the notoriously private couple was spotted having dinner with the Barbadian superstar's family. Speaking to People Magazine, an onlooker who saw the duo at dinner confirmed they were accompanied by Rihanna's mother and one of her three brothers.

"They all stayed a good few hours of the night until dark," the source said. 

The family dinner date comes a couple of months after the duo were photographed enjoying a summer vacation with Jameel's family in Italy. 

The holiday rang serious bells with the couple's fans who thought it was an indication of the fact they were "serious about each other." 

Though the duo has previously been the target of break-up speculations, their cozying up during their time with Jameel's family were enough to quash all rumors. 

Both Rihanna and Jameel prefer to keep their two-year relationship under wraps but have been making more public appearances together in recent months. Earlier this year, they were pictured attending an LA Lakers basketball game. The sports event came just a day after the singer celebrated her 31st birthday with her friends and bae. 

The photos taken of the couple in the sports stadium came months after they were last spotted grabbing dinner at a Malibu restaurant in December 2018.

Rihanna publicly confirmed her relationship with Jameel in June

The star opened up about her love life and relationship with Jameel for the first time ever in a feature published in Interview Magazine in June. 

When the star was asked who she was dating, she told her interviewer, Ocean's Eight co-star Sarah Paulson, to "Google it," but went on to reveal that she was "in love."

During the conversation, Rihanna was asked the redundant "are you going to get married?" and to that she replied: "Only God knows that, girl. We plan and God laughs, right?" 

This wasn't the first time the singer indirectly speaks out about her personal life. In a 2018 interview with Vogue magazine, the star confirmed she was in a relationship. Though she didn't mention her boyfriend by name, people figured she was talking about Jameel. 

"I used to feel guilty about taking personal time, but I also think I never met someone who was worth it before," she said at the time.
