The 'I Will Never Let You Down' hitmaker has reportedly already signed up to the BBC One series, having snubbed The X Factor 2014 panel.
The Daily Mirror reports that the 23-year-old has scooped a "six figure deal" to sit in the famous red chairs.
“Rita is the pop star of the moment, the Beeb are delighted," a source told the newspaper today. "They think she’s going to be a ratings hit and even more popular than Kylie.
“It has taken months of negotiations but Rita is happy and thinks the show is a much better fit for her than The X Factor."
The insider added: “She’ll still be able to get on with her music and it won’t take over her life as much as The X Factor.”
And in further news about The Voice UK 2015 judges, it's said that will.i.am, Ricky Wilson and Tom Jones will ALL be back.
It'll be Will and Sir Tom's fourth series while it'll be Ricky's second time on the show after joining last year.
The source said: “It is pretty set in stone that Will, Ricky and Tom will return.
"They are very much up for being on the panel and they’ve all met Rita, so they are delighted.”
A spokesperson for The Voice commented: “It is too early to confirm speculation. An announcement will be made in due course.”
