Lady GaGa Pulls Shows Due To Illness

Lady GaGa has apologized to fans after pulling some concerts in the US.

Despite rumors saying the singer was "exhausted" following her appearance on American Idol last week, GaGa was actually taken ill with a high fever and virus, forcing her to axe the gigs.

The 'Poker Face' star writes on her official website: "To my beautiful, talented, luminous fans, I am so terribly sad about the postponed performances."

"I wanted to tell you all, that although many assume it's because of Idol, the truth is I have had a high fever and some crazy virus for days, and I am still sick."

"We are very pleased with how Idol went, but after weeks of not a day off my schedule, my team and doctor felt it imperative that I sleep for a few days."

"I could barely sleep in this morning thinking about all of you. And while some I'm sure are inventing curse words for me, the shows have now been moved to bigger venues. For more dancing, more sweating, and more of my props to fit on stage."
