Basically, here are a couple of comments from the interview:

"It was not intentional. It was a costume accident", say Jackson, in an exclusive interview with Ebony.

"It was an accident," she says. "That was basically it."

In another part of the interview:

Ebony: She goes on to say that some television stations didn't run all of her taped apology.

Janet: "Sometimes, they cut out that I said it was an accident," she says. "That's what the media does, that's the way they want it to be told a different way. I probably should have done it live, but there was so much going on at the time that I needed to just get it done. It is what it is."
