Dianna Agron has apologised for her racy magazine photoshoot.

The 'Glee' actress - who outraged parents groups In America when she was photographed for the US version of GQ magazine in a provocative cheerleading outfit - took to her blog to say that the pictures were a mistake.

The pretty blonde actress - who plays Quinn Fabray in the musical school series - insists the saucy images "do not represent who I am".

She added: "They asked us to play very heightened versions of our school characters. At the time, it wasn't my favourite idea, but I did not walk away.

"If you are hurt or these photos make you uncomfortable, it was never our intention. And if your eight-year-old has a copy of our GQ cover in hand, again I am sorry. But I would have to ask, how on earth did it get there?"

Tim Winter of the Parents Television Council said of the magazine shoot, which also features co-star Lea Michele in a series of raunchy poses: "It borders on paedophilia."

GQ editor-in-chief Jim Nelson hit back saying: "I think most people will take the pictures with the wink and spirit of fun in which they were made."

Male co-star Cory Monteith also featured in the shoot but he appears fully clothed.
