Rihanna sure has a thing for athletics. First, she dates L.A. Dodger baseball player Matt Kemp and now she’s holding down the halftime show at the NBA All-Star game. Rocking a massive ruby red ponytail, Rihanna performed a medley of hits, starting out with “Umbrella,” then moving on to “Only Girl,” “Rude Boy,” “What’s My Name?” and “All of the Lights” featuring none other than Mr. Kanye West.Rihanna’s vocals were at times, slightly off. She seemed to fare the best on “What’s My Name.” The song had her voice in a comfortable pocket. Then again, the sound quality was subpar for the whole halftime show. But at the least, Rihanna showed she was committed to putting on a show and her choreography and dance moves were much appreciated. She just needs to keep up her intensity while dancing.Speaking of intense, how about that Kanye West?! He entered the halftime show in a billow of smoke to the triumphant horns of “All of the Lights” in a red jacket and metallic red jeans. The Red Ranger was ready to rock! Now if only he’d announce a tour.But Kanye wasn’t the only guest during RiRi’s set, though he certainly was the grandest. Drake also emerged from the crowd for a flirt action between him and Rihanna on “What’s My Name.” At this point, it’s not clear who Drake prefers to stoke relationship rumors with more: Nicki Minaj or Rihanna. Though Drizzy’s ideal would likely be to bed both.
