WATCH: It's Katy Perry... As You've Never Seen Her Before!

We all know Katy Perry as the mega popstar these days but it was a very different story when she began her career on gospel TV.

New video footage has emerged online of Perry as a young teenager performing under her christened name of Katy Hudson.

The footage was taken from a Christian TV channel a few years ago and shows the 'Firework' singer totally make-up free with dark bobbed hair, singing a song called Search Me while strumming on an acoustic guitar.

Perry, who was born Katheryn Hudson, was a gospel singer growing up in Santa Monica, California and sang in the church run by her pastor parents.

Her childhood and rise to pop stardom has been documented in her new movie Part Of Me, which opened on Thursday with a modest $3.1 million gross, according to The Hollywood Reporter.

Experts expect its total for the weekend will finish in the low-to-mid teens millions-wise - not too bad considering it only cost $12 million to make, but only enough to score an underwhelming chart placement of No. 5.

By comparison, Justin Bieber's Never Say Never managed $29.4 million in its opening weekend last year, and Hannah Montana: Best of Both Worlds Concert Tour collected $31.1 million in 2008. Both of those, however, were released outside of the competitive summer period.
