It is her fifth hit from her album Teenage Dream and she now shares the joint honour with Michael Jackson's Bad album which was released in 1987.
But did she cheat her way to the top? Some commenter's have pointed out some of the ways she got her #1's to #1
The studio version of Last Friday Night was unable to get to #1 alone so she released an remix a few days ago and for "charting purposes" it charted under the name "Last Friday Night". She also reduced the price of her songs to 69c in a desperate bid to try and get to #1.
Michael Jackson NEVER did this. He never released new remixes to help him get higher in the charts nor did he have to lower his prices. I have no idea if Katy got the other #1's fairly (If she did, that's really awesome and congrats to her!) but one thing for sure is that she does not deserve this title until she is able to get one more #1 fairly and without pulling this crap off.
What do you think did she cheat her way to equal Jacksons record?
Katy's other tracks that topped the charts from the album are California Gurls, Teenage Dream, Firework and ET.
Michael's songs that made it to number one are I Just Can't Stop Loving You, Bad, The Way You Make Me Feel, Man in the Mirror and Dirty Diana.
Until next time keep rockin'
