Paloma was a coach on The Voice in its final year on BBC One alongside Will.i.am, Boy George and Ricky Wilson.
Now in a recent interview, Paloma has suggested that rival series The X Factor is in fact the better show.
And it's all because of Simon Cowell.
Paloma told the Daily Express: “He’s a b****y determined man. He is a high-achiever by nature and he believes that he wouldn’t ever do anything that wasn’t a success.”
She explained: "He’ll do everything he has to to make it a success, and there’s no one person doing that on The Voice – there’s no one person saying, ‘I am determined to make sure this, you know’.
“Everybody else on The Voice has their own personal career whereas Simon’s career is to make other people’s careers. That’s his career.”
The singer - who went to Number 1 with new album The Architect last year - previously suggested that even big stars wouldn't do well on The Voice UK.
Paloma told Attitude magazine (via the Daily Mirror): “I don’t think David Bowie would have made it through on The Voice, never mind my chances, or those of Boy George.”
Recalling the final series on BBC One, Paloma faith spoke of her act Jordan Gray and Boy George's contestant Cody Frost.
“At the end of the finals Boy George and I looked at each other - it was live and he just went, ‘We’re f*****!’" she said. “I tried to help make the first transgender pop star the winner and George had this gothic lesbian who he was championing.
"And we were both obsessed by each other’s choice.
“When the votes started coming in there was a modicum of hope for us that together we might do something amazing and innovative and exciting, then we were like, ‘nope, we are f*****!’"
Paloma also claimed that The Voice UK's 'fast track' process didn't help create long term success.
“I do feel like it’s unrealistic the time frame they’re given on The Voice,” she said. “Ten years of singing in pubs with no one listening to me was vital to me as an artist and you can’t get that in a couple of months.”
The Voice UK continues Saturday nights on ITV.
Olly Murs joins the show this year alongside Will.i.am, Sir Tom Jones and Jennifer Hudson.
