Katy Perry Ties With Rihanna

The track comes from Teenage Dream: The Complete Confection, the special edition of her Teenage Dream album.

Katy now ties Rihanna's record for the most number 1's in the nearly 20-year history of Billboard's Nielsen BDS-based Mainstream Top 40 chart.

"The achievement is even more impressive given that while the chart launched the week of Oct. 3, 1992, Rihanna didn't first grace the list until 2005 and Perry didn't arrive until 2008. Of the acts with the most Mainstream Top 40 number 1s, the top seven are women. After Katy and Rihanna, Lady Gaga, P!nk and Britney Spears each have seven lead�ers, while Beyonc� and Mariah Carey fol�low with six apiece," reports Billboard Magazine.
