The 'Price Tag' popstar, who acted as a guest mentor on last year's X Factor, said that she was a fan of Simon Cowell's reality formats, but insisted that the BBC offering would fill a different gap in the market.

"Comparison has become so trendy, but I think this show stands by itself," said Jessie.
"I think other shows are great, but this is the one that I wanted to be part of. It's about vocals, it's about music, it's about talent, it's about The Voice. It says it in the title.
"I think Britain's Got Talent is wonderful, I think The X Factor is wonderful, but I think this TV show is something that television needs."
Talking about possibly collaborating musically with her fellow Voice coaches, she added: "Defos. Tom Jones, Jessie J. We're going to be in the studio one day. That might even be a lyric in the song."
The Voice UK launches on Saturday, March 24 at 7pm on BBC One.
