"I honestly would collaborate with a lot of people, but everyone usually says no," she admits. "I'm not kidding you. I have legitimately asked several people that I'm not going to call out, and that's cool, but I don't know."
"I ask good people, I don't want to sing with crap people, so I mean, I ask people who are great vocalists, but I'm not going to point out anyone," she adds. "I have asked several people ... Sometimes I feel like I have the plague, or leprosy, they're like, 'If you get too close ...' I don't know."
Some speculate that one reason could be her highly publicized feud with legendary music executive Clive Davis, in which she ended up openly calling him a "bully" and attempted to discredit his memoir The Soundtrack of My Life.
She also hasn't been too shy about openly criticizing other artists in the past.
After watching the 2013 MTV Music Video Awards, with performances by Lady Gaga, Katy Perry and of course -- Miley Cyrus' memorable duet with Robin Thicke -- she tweeted out some pretty harsh words.
Just saw a couple performances from the VMA's last night. 2 words.... #pitchystrippers
Nevertheless, Kelly's pretty happy that she was able to collaborate with "All of Me" singer John Legend for her new album Piece by Piece, out March 3.
"I got John Legend to say yes, and he's cool," she gushes. "I can get country artists to sing with me and John Legend! I'm gonna keep John Legend. He's super credible and talented. I feel very good about myself with that one."
