Off the back of a powerful Grammy performance, it was no surprise ‘Part Of Me’ would sell like hot cakes.

Over the past week, Billboard had predicted digital sales between 400,000-420,000, and they weren’t too far off, with the song selling a massive 411,000 in seven days, enough to ensure a #1 chart debut.

‘Part Of Me’ becomes the chart’s 20th #1 debut in Billboard history, and the first to garner the accolade since Lady GaGa, who also introduced ‘Born This Way’ in a same manner on the Grammy’s stage, selling over 448,000 in three days last year’s February.

As this week’s chart was revealed, Perry took to her Twitter to thank her fans,

Thank U to all the AMAZING radio stations playing “Part Of Me” & the Katycats that keep requesting the ish out of it! #ioweuandiwilldeliver

As previously stated, Katy’s 7th #1 overall, won’t count as a single from Teenage Dream, thus she remains tied with Michael Jackson for producing most number one singles off one album alone.

It has been a wonderful year for Perry, a critically-acclaimed double platinum sophomore release, 5 consecutive number ones, all 6 Teenage Dream singles reaching the top of the Pop and Dance Charts alike (7 counting the unofficial entry of ‘Peacock’ in the latter), a sold out world tour, and what is looking to be a solid re-release celebrating the album that catapulted her beyond success.
