Simon Cowell Fired Demi Lovato From X Factor? Simon said he knew about the leave

Simon Cowell admitted that he knew that singer Demi Lovato was leaving her 'X Factor' judging  seat.

After 3 seasons, Lovao will be taking time for her own music career. Cowell confirmed to Hollywoodlife, "I knew she wasn't coming back because she's [going to be] touring," he said.

"We always knew that. Two seasons was good," Simon added. "In terms of next season, I believe it will be back. It will have a different look to it."

For Lovato the leave is bittersweet and said that she enjoyed interacting with contestants with her celebrity friends,

 "What I'm going to miss the most about this experience is probably being able to sit next to Kelly [Rowland] and Paulina [Rubio]," she said. "They been so incredible to me."

She told Hollywoodlife, "Getting to help mentor contestants achieve their dream - you know, you get emotionally invested in their dreams and you get really passionate about helping them out and wanting them to have an awesome performance."
