Katy Perry's 'PRISM' Hits 1 Million Sold In the US

Katy Perry has officially scored three million-selling albums.

Her newest effort, "PRISM," passed the 1 million sales mark this week, according to data from Nielsen SoundScan. The album sold 51,000 copies last week, bringing its cumulative tally to 1,020,000 in 11 weeks on sale.

The album follows 2008's "One of the Boys" and 2010's "Teenage Dream" in the million-selling category in the U.S. The latter took 20 weeks to hit that amount, going on to be certified double-platinum by the RIAA.

The success of "PRISM" stems from its first single, "Roar," which spent two weeks at No. 1 on the Hot 100. While second single "Unconditionally" could only find a No. 14 peak, newest single "Dark Horse" rose 11-6 on the Hot 100 this week, becoming the singer's 13th top 10 hit.

The sales could keep coming in droves if "PRISM" yields more top singles. "Teenage Dream" hit the peak of the Hot 100 with five different singles, with the album's "Complete Confection" re-release adding a sixth in "Part of Me."
