Rihanna & LeBron James Hook-Up, Dumps New 'Boyfriend' Karim Benzema!? NBA Playoffs, Savannah Brinson Cheating 'Side Chick' Scandal Exposed, Dating Drake's Ex?

Apparently, Cleveland Cavaliers superstar LeBron James is now involved in some off-court drama following Game 1 of the NBA playoffs...

Did James cheat on longtime sweetheart Savannah Brinson with "Pour It Up" songstress, Rihanna!?

According to the seedy gossip webloid MediaTakeOut.com, the 27-year-old Barbadian beauty randomly attended the game in Oakland, California on Thursday evening (June 4). Apparently, she flew from Los Angeles to San Francisco on a private jet chartered by Nike (and sponsored by James).

After the Cavaliers lost in overtime to the Golden State Warriors (with a score of 108-100), RiRi was surprisingly spotted backstage, "yelling like a groupie" for the former Miami Heat player:

@SpearsNBAYahoo: "For some odd reason, Rihanna screamed 'LeBron...' several times by Cavs locker room."

So, here's where things get shady...

James ultimately left Brinson home while he travels around during the series. Supposedly, he wants her to stay for the benefit of their three young children. But MTO suggests that in reality, he just wants some freedom.

The 30-year-old baller began dating Brinson in high school. He proposed on New Year's Eve in 2011, and the couple officially tied the knot on September 14, 2013. Obviously, James never had the chance to "hook-up" with random fans...

Now, rumors suggest that Drake's ex is James' first secret "jumpoff." Right...

But did RiRi and James actually meet after the game? Details surrounding this latest NBA "cheating scandal" still remain unconfirmed. In fact, the "Diamonds" crooner is allegedly dating Real Madrid soccer heartthrob, Karim Benzema. They were spotted partying together in NYC earlier this month.

Readers are now sounding-off on this rather over-sensationalized update:

Welp: "Rihanna needs to stay away from married men, i don't care how well she knows him it's inappropriate."

Guest: "She can't be fuc*ing everybody. He does hang around with Jay-Z so, I'm sure she knows him. You can't even call people's name anymore."

Philly Jawn: "Yeah ok is that why they lost? Any way she dont want to see Savannah in these streets."
AK: "So the receipt is... A random tweet??"

lindsayll: "I will slap the head off Rihanna if she eff up this ring!! Girl bye! See dis man after the SHIP!!"

RiRi does love her athletes - but if anything she better not mess-up James' game!
