Rihanna's Work stays put atop Billboard Hot 100

Rihanna is continuing to steam up the pop charts after scoring a second week at number one with Work.

The R&B star's sexy collaboration with Drake, her 14th Hot 100 number one, remains atop the Billboard countdown, fending off Justin Bieber's Love Yourself, which sits at two.

The remainder of the new top five is also unchanged: Twenty One Pilots' Stressed Out is at three, while Bieber's Sorry takes fourth place and Flo Rida's My House rounds out top flight at five.
