Following her at the top spot are Katy Perry and Rihanna sitting at the runner-up and third positions respectively.
Pregnant pop star Pink has good reason to celebrate after flying to the top of the U.S. pop chart with her new single "Raise Your Glass". The singer climbs up one spot to bump Rihanna's "Only Girl (In the World)" into third place, while Katy Perry fills in the gap at two with "Firework".
Bruno Mars creeps up to number four with "Just the Way You Are" and scores a second entry in the top 10 with "Grenade" at 10. But he's not the only one seeing double - Rihanna rounds out the top five on the Billboard Hot 100 with "What's My Name?", her collaboration with Drake.
"Greatest Hits... So Far!!!", the compilation album in which "Raise Your Glass" appears, debuted at No. 14 on Billboard Hot 200.
