Rihanna is thought to be dating basketball player JR Smith.

The 'Where Have You Been?' singer was spotted with the New York Knicks shooting guard while at an event in Florida.

The stars were apparently seen spending time together in Miami over the weekend, and an insider has claimed that Rihanna and JR were both in attendance at the Fontainebleau Hotel's LIV nightclub on Friday (25.05.12) and met up again the next evening.

The insider told The New York Daily News: ''[Rihanna and JR were] definitely hanging out.''

It comes only days after the sportsman was briefly jailed for driving without a license in the city.

Meanwhile Rihanna - whose real name is Robyn Fenty - was recently banned from Kanye West's dressing room by Kim Kardashian during his recent London concerts.

The reality TV starlet doesn't want her 34-year-old boyfriend hanging out with other women on his own and with Rihanna's flirtatious reputation, she wasn't taking any chances when she wasn't at The O2 Arena for his 'Watch The Throne' tour shows with Jay-Z.

Kim is believed to have not been a fan of the 'You Da One' singer since she was romantically linked to her brother Rob Kardashian several months ago.

A source told The Sun newspaper: ''Kim doesn't want women near him unless she is there - even friends. The fact Rihanna was linked to Rob probably didn't help.''
