Demi Lovato is great friends with all her colleagues on The X Factor US.
The singer featured on last year’s The X Factor US judging panel alongside Simon Cowell, Britney Spears and L.A. Reid.
The 20-year-old insists she shared a close bond with her fellow judges.
"Professionally, it's been amazing to work with [Britney], but behind the scenes as well she's a really sweet girl and I'm really lucky I got to work with her and L.A. and Simon," she gushed to Australian radio show hosts Kyle and Jackie O.
"But even behind the scenes with Simon, I love him to death but he does get on my nerves."
Britney and L.A. have left the talent series to concentrate on other projects, with their replacements yet to be announced.
Demi and Simon are known for teasing each other on the show.
However, they have a lot of respect for each other and the former Disney Channel star is pleased with her experience on The X Factor.
"It was just something that I felt really nervous about and it turned out to be really great," she smiled.
"I am the type of person that doesn't hold back - especially when it comes to Simon Cowell."
Demi doesn't just get along with her colleagues on the show.
Recently, she bumped into Gwyneth Paltrow and the two stars posed for a photograph together.
"She's really sweet, I love her. She's so down to earth and she's really cool," Demi revealed.
