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. Barnes told the website, " Rihanna's my friend right now, so we'll see where it goes. [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." 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.
