Pop star Rihanna slammed NBA player Matt Barnes over dating rumors Sunday on Instagram.

The 27-year-old singer took to the social media site after the 35-year-old Memphis Grizzlies small forward insinuated they are dating in an interview with TMZ published the same day.

"Rihanna's my friend right now, so we'll see where it goes," Barnes told the website. "[There's] possibly [a future there]. I think it's past the crush stage a little bit." When asked where they went on their first date, however, the NBA player said, "All that is rumors."

Rihanna shut down speculation with a screenshot from the interview, writing, "#bishwhere #thedevilsaliar #shesnotthatintoyou #shesnotintoyouatall #shesneverevenmetyou #thisactuallyhurtmyfeelings #defamationofcharacter."

Barnes had previously made the star his #WCW, or Woman Crush Wednesday, on Instagram, and gave her a shout out on Twitter after Rihanna saw the Lakers play the Grizzlies in 2012. The singer was last linked to Formula 1 driver Lewis Hamilton.
