Last Friday Night Puts Katy Perry in History Books

"Last Friday Night (T.G.I.F.)" is officially the #1 song in the country. This puts her in very exclusive company, because this is the FIFTH song off of her pleasant-smelling "Teenage Dream" album to reach #1 on the Billboard the charts. Only one other artist in history can say that...

In 1987 Michael Jackson's "Bad" album produced 5 #1s:

- I Just Can't Stop Loving You

- Bad

- The Way You Make Me Feel

-Man in the Mirror

-Dirty Diana

Katy Perry's "Teenage Dream" as of this week has also produced 5 #1s:

- California Gurls

- Teenage Dream

- Firework

- E.T.

- Last Friday Night (T.G.I.F.)
