With the rise of her latest single "Roar," Katy Perry has tied Rihanna for the record for the most No. 1 songs in the history of Billboard's Pop Songs radio airplay chart. Both singers have 10 toppers to their name.


Rihanna's "Stay" gave her the title earlier this year, only to be tied by "Roar," Perry's lead single off the upcoming album "Prism."


The track follows past No. 1s from Perry including 2010's "California Gurls," "Firework," and "Teenage Dream." Behind Perry and Rihanna are P!nk with nine hits, and Lady Gaga and Britney Spears tied with seven each.


Perry's "Prism" is scheduled to hit stores on Oct. 22 and may provide the singer with even more No. 1 hits. The 13-track album features production by Dr. Luke, Klas Ahlund, and Sia, among others.
