Pink has scored a third week at the top of the U.S. pop charts with her Nate Ruess duet Just Give Me A Reason.

The track keeps MACklemore & Ryan Lewis from claiming a second 2013 chart-topper with Can't Hold Us, which stays put at two on the new countdown.

The duo's former number one, Thrift Shop, drops one place to four, while Rihanna's Stay jumps up three spots to three and Justin Timberlake's Mirrors rounds out the new top five at five.
