Katy Perry has earned her seventh No. 1 song with ‘Part of Me,’ the song she performed at the 2012 Grammy Awards, which enters the singles chart at No. 1 this week.

‘Part of Me’ is the first song to debut at No. 1 since Lady Gaga‘s ‘Born This Way’ at this time last year. This has to be a sweet accomplishment for Perry since the track is about her ex-husband, Russell Brand, as seen in the lyrics, “So you can keep the diamond ring / It don’t mean nothing anyway / In fact you can keep everything / Except for me.”

Since ‘Part of Me’ is from ‘The Complete Confection,’ the repackaged version of ‘Teenage Dream,’ Perry could claim to have six No. 1 hits from that album. But Billboard already announced that it considers the repackaged edition to be a brand new release, meaning that Perry’s ‘Teenage Dream’ will remain tied with Michael Jackson’s ‘Bad’ for the official record of five No. 1 hits from a single album.

Behind Perry, Adele‘s ‘Set Fire to the Rain’ holds down No. 2 on this week’s chart, while ‘Rolling in the Deep’ and ‘Someone Like You’ both return to the Top 10. Whitney Houston‘s ‘I Will Always Love You’ rises from No. 7 to No. 3 as fans continue downloading the classic track. Kelly Clarkson‘s ‘Stronger (What Doesn’t Kill You)’ drops from No. 1 to No. 4.
