Singer Sheryl Crow has claimed that she saw Michael Jackson doing "really strange" things when she toured with him in the '80s.

During an interview with The Telegraph, Crow revealed she has not watched HBO's documentary Leaving Neverland, but was around "for some things that I thought were really strange." 

Crow was a background singer during Jackson's Bad tour and later starred in his music video for “Dirty Diana”. 

"I haven't seen the documentary, and I don't want to see it," she said. "I was around for some things that I thought were really strange, and I had a lot of questions about."

Crow was then asked if she ever wondered about the children who traveled with MJ on his tour:

 "I think that there were a lot of exceptions made because of the damage that [Jackson]... I mean, he didn't intentionally project it, but it was part of his aura – this almost being untouchable and almost alien-like [figure]," she told The Guardian in a separate interview.

"And yeah, I mean, I'm sad, and I'm mad at a lot of people. I feel like there was just a huge network of people that allowed all that to go on. It's just tragic."

She did not go into depth about what these "strange" things were.
