Katy Perry bounces back to the top spot on the Billboard Hot 100 as “E.T.” featuring Kanye West rises 2-1 and displaces Rihanna’s “S&M.” It’s the tune’s fifth non-consecutive week at the top. “S&M” drops to No. 4.

The jump is likely due to Perry’s performance on “American Idol” last week , which propelled digital sales.

Adele, whose “21” hops back to No. 1 on the Billboard 200, sees first single “Rolling in the Deep” rise 6-2. The Black Eyed Peas’ “Just Can’t Get Enough” stays at No. 3. Jeremih’s “Down On Me” falls 4-5.

Rounding out the top 10, Bruno Mars’ “The Lazy Me” jumps 11-6. Jennifer Lopez’s “On the Floor”  and Chris Brown’s “Look At Me Now,” flip positions as Lopez drops 7-8. Ke$ha’s “Blow” moves 12-9 and Cee Lo Green’s “F*** You” drops 10-5.

Lady Gaga’s “Judas” drops 10-12.
