The newbie coach is on the panel for her first live show tonight and has accused her rivals of "playing games".
"They’ll never admit it!” she told The Sun's TV magazine today. “I can see people’s little tactics going on.
"Not in bad ways, just in funny ways – and they pretend they don’t know they’re doing it. I’m not giving you any names because I’ll be in trouble.”
Rita decided on Clark Carmody, Karis Thomas and Joe Woolford as her final three and claimed: “Every single person on my team is current and could do something right now in the music industry."
The 24-year-old's choice of finalists caused a bit of controversy last weekend with many accusing her of making the decision before the acts had performed at the knockouts.
Even Will.i.am was left stunned when Rita took Clark through, reacting "Are you serious?!"
It's left Clark with an uphill battle ahead of tonight's show and he admitted: "I feel like I’ve got something to prove in the live shows because, in the knockouts, I froze before I started singing – the fear got the better of me. "
The Voice airs from 7:15PM tonight on BBC One.
