Demi Lovato: 'I Miss Britney Spears On X Factor USA'
But judge says she's getting on great with the show's new recruits...
"I do miss [Britney and LA]," she told Digital Spy. "We spent a lot of time together and we'd formed those bonds, but it's a new chapter now and I'm excited to start a new experience with new people."
But the pop star stressed that she had no issue with the show's new judges, Kelly Rowland and Paulina Rubio.
"I love the new judges, they're amazing," she continued.
"Kelly is so much fun to work with - she's got a great energy about her and we connect really well. It was just an instant, off-the-bat kind of thing. Paulina is doing great as well - she's really, really huge in South America and I'm glad the show is representing that side of things more."
Fox exec Mike Darnell recently promised major changes to the show's format this year.
