Did Lady Gaga take it too far this time?

The outrageous singer rolled out in a wheelchair during her performance in Sydney, Australia on Wednesday, which some fans found offensive - as did some disability organizations and advocacy groups, RadarOnline.com has learned.

"I haven't seen Lady Gaga's performance, but respect her artistic expression as an artist. 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," Founder of the Life Rolls On Foundation, Jesse Billauer, told RadarOnline.com in an exclusive statement.
