Pop singer Katy Perry used to pray for big boobs.

The quirky I Kissed a Girl star revealed: “I remember really vividly kneeling by my bed as a nine-year-old, saying my prayers and asking God to give me boobs that were so big that if I laid on my back, I wouldn’t be able to see my feet.

“Eventually, that request was granted.”

The busty singer added: “A bit of divine intervention displays the power of prayer.

“Every time before I go on stage, or go out where I know there will be a lot of Press, I take a skipping rope and spend about 10 minutes, fully clothes, skipping.

“I look like Rocky.

“This way, I can ensure that everything is firmly in place and I won’t have a wardrobe malfunction.

“Don’t want those boulders doing a show of their own.”
