Contrary to gossip reports, Rihanna is not dating basketball player Matt Barnes. In fact, she doesn't even know who he is. The R&B songstress put Barnes on blast for lying about dating her.

It all started when Barnes was asked by TMZ Sports about his relationship with RiRi. It's been reported that he and the singer went out on two dates. The Memphis Grizzlies player may have misspoke when he told the camera guy they were "just friends" and something could happen in the future.

However, Rihanna went on Instagram and made it crystal clear that she has never met Barnes or have an interest in him. In a string of hashtags, she wrote: "#bishwhere #thedevilisaliar #shesnotthatintoyou #shesnotintoyouatall #shesneverevenmetyou #thisactuallyhurtmyfeelings #defamationofcharacter."

So are you confused as we are? Matt Barnes has some explaining to do.

For now, it looks like Rihanna is happy dating her rumored beau racing car driver Lewis Hamilton.
