Rihanna Takes Rich BF to Lakers Game, Team Delivers Comeback Victory

You think LeBron James and the Lakers were gonna let Rihanna down on the night of her birthday celebration???! Hell no!!

RiRi took her superrich Saudi boyfriend to Staples Center on Thursday to cheer on her favorite NBA player on the night after her 31st birthday ... and the team delivered one heck of a gift!!!

Check out the pics of Rihanna and Hassan Jameel in a private box -- going berserk as the Lakers came back from 19 down to beat the Houston Rockets ... one of the hottest teams in the NBA.

Of course, Jameel is a bit of a baller himself -- in 2017 his family was reportedly worth $2.2 BILLION -- which made them the 4th richest family in the Arab world.

Jameel started dating Rihanna in 2017 and by the looks of these pics, they're still going strong.

Other huge stars at the game -- "Wheel of Fortune" star Pat Sajak, Denzel Washington, French Montana and Jimmy Iovine.

They picked a great game to attend -- the Lakers were getting destroyed for the first 3 quarters before LeBron activated "playoff mode" and went nuclear on everyone ... exploding for 29 points, 11 rebounds and 6 assists.

The Lakers ended up winning the game 111 to 106 -- boosting the Lakers' record back to .500.

Meanwhile, the Rockets' James Harden extended his 30-point game streak to 32 games, the 2nd longest 30-point streak in NBA history.

By the way, Lakers officials gifted Rihanna her very own customized "Bad Girl RiRi" Lakers jersey, but she didn't wear it ... instead, opting to rock her #23 LeBron James threads.

One last thing ... every year LeBron has won an NBA title, Rihanna has dropped a new album -- and there are rumors she's working on a new album right now.

So, good juju for the Lakers?
