Celebrity snapper ANNIE LEIBOVITZ has come under fire for pushing stars to go too far in photoshoots.

The celebrated photographer hit the headlines earlier this week (beg28Apr08) when provocative shots she took of 15-year-old Miley Cyrus for Vanity Fair magazine first appeared.

The teenager, Leibovitz and Vanity Fair bosses have been blasted by the media and family values groups for one shot in particular, in which Cyrus poses topless, wrapped in a satin sheet.

Both Leibovitz and Cyrus have since stated the photos have been misinterpreted in the media, with the snapper calling the "beautiful" satin sheet photo "a simple, classic portrait, shot with very little makeup."

But now stars are coming out to expose Leibovitz's techniques.

Former teen icon Donny Osmond, who has already criticised Cyrus for posing seductively, has now taken aim at the photographer, recalling one of the first times he met her for a Rolling Stone magazine photoshoot.

He says, "I was about 14 or 15... It's always, `Push it a little farther.' She went a little too far with that picture of Miley."

And speaking on America's The Tonight Show on Thursday (01May08), Robin Williams confessed, "She will get you to do anything. She'll (be) like, `Put a rogue flare in your ass, go out in that field, let's shoot it!'

"She had a picture she wanted to do with Eddie Murphy and I, where she wanted Eddie to be in white face (makeup) and me to be in Black face, and I said, `Listen, there's not a lot of mimes that are going to kick Eddie's ass, but the painted Black face may not go so well for me.'"
