Robin Thicke’s ‘Blurred Lines’ Reign Ends, Katy Perry ‘Roars’ To No.1

Robin Thicke's chart-topping reign on the Billboard Hot 100 has come to an end.After a strong 12-week run at no.1, Thicke's "Blurred Lines" has slid to no.2 thanks to the advancement of Katy Perry's hit single "Roar."

Fresh off a performance at the MTV Video Music Awards, Perry scored her eighth Hot 100 no.1, with "Roar," Wednesday, which rose 2-1.

According to Nielsen Soundscan, Perry's "Roar" sold a whopping 448,000 copies (downloads) for the week ending September 1. That is a 14 percent rise in comparison to last week. "Roar" is also up on the streaming songs tally, with 5.4 million in streams.

"Roar" becomes Perry's eighth Hot 100 No. 1. She first led with "I Kissed a Girl," which began a seven-week command (her longest) the week of July 5, 2008. In that span, Perry has quickly scaled the list of the women with the most No. 1s in the chart's 55-year history. Among female soloists, only Mariah Carey (18), Madonna, Rihanna (12 each), Whitney Houston (11) and Janet Jackson (10) have totaled more leaders. Among all artists, Perry is one of just 16 acts with at least eight No. 1s; the Beatles lead with 20 Hot 100 toppers," reports Billboard.

"Roar" leads Perry's forthcoming album, "Prism."
