Matt Barnes is living a very curious fantasy -- one in which he's dating Rihanna, or about to date Rihanna or something. This is all very confusing. TMZ cornered the Grizzlies forward after a softball game and asked him about his rumored relationship with the singer. He said there was "possibly" a future together between the two.

There's just one problem for Barnes: Rihanna says they've never met.

Rihanna's just telling it how it is. Matt Barnes has got some explaining to do.
