The diva roars in atop the Billboard 200 with 286,000 copies sold -- her best week ever.

Katy Perry logs the biggest week of the year for a female artist on the Billboard 200, as her new "PRISM" debuts at No. 1 with 286,000 copies sold, according to Nielsen SoundScan.

She surpasses the previous high for 2013's ladies: Miley Cyrus' "Bangerz," which launched with 270,000.

"PRISM" is Perry's second No. 1 album, following her last release, 2010's "Teenage Dream." "PRISM" also captures Perry's biggest sales week yet, stepping ahead of her previous high-water mark, when "Teenage Dream" launched with 192,000.
