Last night, pop superstar Katy Perry released two new songs -- five days before the records' "Unconditionally" and "Birthday" scheduled release on Tuesday Oct.  22nd.

The two new tracks are off the singer's forthcoming album, Prism (Deluxe).

Here's a little info about the songs... 'Birthday' is an R&B dance track which has been likened to Whitney Houston's early singles. And 'Unconditionally' (produced by Dr. Luke) is a four-minute love song, and features the lyrics; "I'll walk through this storm, I would / All because I love you."

According to Channel24:

"It is rumored Katy will perform Unconditionally - set to be her next single - live for the first time when she appears at the MTV European Music Awards (EMAs) on 10 November."
