R&B singer R. Kelly is blaming rumors for the cancelation of a scheduled performance at the University of Illinois at Chicago after students and staff petitioned against his appearance because of sexual misconduct allegations.

I dont know why they canceled the show. Ive never heard of a show being canceled because of rumors, but I guess theres a first time for everything, Kelly said in a video posted to Twitter on Sunday.

Kelly has been dogged by dozens of allegations of sexual abuse and misconduct over the years, including operating a sexually abusive cult and producing child pornography a crime he was acquitted of. A woman recently accused him of infecting her with an STD.

Kelly, a Grammy-winning Chicago native, hinted at legal action over being booted from Love Jam concert, scheduled for May 5 at the university pavilion.

Im going to try to get to the bottom line of it, you know, as far as my lawyers are concerned, and see exactly what happened and why I was canceled, he said.
