The first time Drake showed up on a Rihanna song was "What's My Name," and it promptly went to number one on the Billboard Hot 100. Funny how history repeats itself. 

Rihanna and Drake's latest collab, "Work," has been holding down the top spot for the last 4 weeks, and Billboard has announced today that the single will continue its reign for a fifth. For the time being, the song remains unchallenged, with Justin Bieber's "Love Yourself," the song Rih unseated sitting tight at number 2. 

Meanwhile, Ariana Grande's "Dangerous Woman" has debuted at number 10, and if it doesn't suffer the same fate as her previous (now scrapped) single, "Focus," it could continue to rise from there. Should Rihanna be worried?
