Actress Holly Robinson Peete has been an outspoken autism research advocate, following her son's diagnosis. Now, Robinson Peete is advocating once again - but this time, it was an apology that she wanted after rapper J Cole used a derogatory word for disabled people in a song recorded with fellow rapper Drake.

Robinson Peete says her 15-year-old autistic son is a huge fan of the two artists and came to her after listening to a song by the two, wanting to know what the lyrics meant. In an interview on Access Hollywood Live, the actress said she had to re-read the lyrics herself several times to make sure there wasn't some context she was missing. When she realized the intended use was blatant, she was outraged.

"My son is struggling to fit in, and I mean struggling," she said, "so when I see an artist with this kind of following who is writing not just 'autistic' but is trying to make it the new 'R word'? That's not going to happen on our watch."

She then asked J Cole for apology ... and she got one.

"I was instantly embarrassed that I was ignorant enough to say something so hurtful," the rapper said in a statement. "What makes the crime worse is that I should have known better. I feel real shame. You have every right to be angry. You deserve medals, not disrespect. I hope you accept my sincere apology."

It's still unclear as to whether or not the lyrics will actually be removed, since J Cole was only guest-appearing in the song which is intended to be released on a Drake album.
