Rihanna allegedly replies to a fan about J.R. Smith and their relationship Instagram

Rihanna is over the rumors that she's seeing New York Knicks guard J. R. Smith. Since her most recent breakup with Chris Brown, reports have surfaced that she has been dating Smith.

Smith, 27, has dated a string of video vixens such as Tahiry, who was featured on the reality show “Love & Hip Hop New York.” He was recently spotted sitting in the VIP section with Rihanna at a party at Greenhouse in SoHo on April 24 -- the night before Game 1, which was an afternoon game.

The Knicks reserve has since been criticized for having a lackluster performance in the NBA playoffs. Rihanna, 25, has denied they're dating, reportedly going as far as to call Smith “thirsty” and even bashing the Knicks, who are down 2-3 against the Indiana Pacers. On Instagram, a fan named @pervuvian_gawd reportedly reposted a message Rihanna wrote to him after he blamed Rihanna for Smith’s struggles on the court.

Earlier this month, Brown unfollowed Rihanna on Twitter when pictures were posted of her kissing an apparent fan after one of her performances in New Jersey. Brown then confirmed that he and Rihanna are no longer dating after celebrating his 24th birthday at a Los Angeles, Calif., nightclub with ex-girlfriend Karrueche Tran.
