Washington, Feb 20: An unwell Katy Perry has urged her fans to pray for her quick recovery from influenza so that she can make it for her European tour dates.

Perry, 24, was not well when she attended the Brit Awards in London on February 18, and her condition has not improved since then.

She is worried for her tour, scheduled to begin on February 22.

The `I Kissed a Girl' singer admitted in a posting on her website that her hotel room "smells like death", and that she is doing everything to beat the bug.

"I can't tell you how bad I feel right now. Last night I was sweatin'' it out... I have the doctor on speed dial if the fever gets over 101/102," Contactmusic quoted her as saying.

"I thought I was invincible and then my body decides to show me otherwise.

"I'm stuck in bed for the next couple of days as I should be... I'm gonna go back to sweatsville and try and sleep it off some more... I gotta get better; I'm starting (a) tour on Sunday here (in London)... so say a little prayer if you think of it," she added. (ANI)
