Lady Gaga's wheelchair performance in Sydney, Australia, is certainly one of her biggest failed attempt to woo her audience. Rather than impressing anyone, all that the act has done in fact, is to have disappointed some disability organizations and advocacy groups.

The Italian- American singer who is widely known for her explicit usage of outrageous props and clothing has this time offended her fans with the wheelchair act.

I haven't seen Lady Gaga's performance, but respect her artistic expression as an artist, Radar Online quoted founder of the Life Rolls On Foundation, Jesse Billauer, as saying.

Since this isn't the first time she has used a wheelchair in her performances, I invite her to learn more about the 5.6 million Americans who live with paralysis.

They, like me, unfortunately, don't use a wheelchair for shock value, he said.

Life Rolls On, a subsidiary of the Christopher and Dana Reeve Foundation, strongly feels that the wheelchair shouldn't have been used as a prop, just to draw attention.

I extend a personal invitation to Lady Gaga to attend one of our Life Rolls On events where quadriplegics and paraplegics surf, skate, and snowboard, so she can see how much is possible beyond a wheelchair, Billauer said.

Maybe that will be most shocking to her of all, he added.
