NEW YORK • Katy Perry has kept her winning streak, with her new album Witness landing on top of the Billboard album chart.

The feat was also achieved by her previous releases - Prism in 2013 and Teenage Dream in 2010.

There was speculation last week that Witness might not give her the coveted hat-trick, given the not-so-stellar response to singles from the new album.

While she has collected 14 Top 10 hits throughout her career, singles from Witness have struggled, with Swish Swish sitting at No. 83 and Bon Appetit at No. 98 ahead of the album's release, noted The New York Times.

Still, Witness - helped by tonnes of publicity efforts by Perry, including a livestream of what she did at home - saw off contenders for the No. 1 spot, selling 162,000 copies in its first week.

It was streamed another 19 million times for a total of 180,000 album equivalent units, said Nielsen Music.

Perry is only the second woman to top the album chart this year, after Halsey bagged bragging rights last week with her Hopeless Fountain Kingdom release.
