The new X Factor judge has hinted she could once again be teaming up with the American singer for the penultimate stage of the competition which this year is LIVE.
Speaking to Free Radio, Rita teased that she "definitely had got a few ideas in mind about who I would like to join me, but I am definitely not going to let anybody know, you’ll have to wait and see!"
Speaking about Chris Brown and the pair's recent single together, she continued: "I am musically such a fan of Chris’s work and I have been for such a long time."
"I really just thought vocally, his voice really suited this record, and I approached it with just that in mind. Musically it worked perfectly."
However Rita has had to defend her collaboration with the controversial musical star.
She hit back at the critics in a separate interview with Glamour magazine: "Chris Brown is strong, powerful and someone that is important to me personally and professionally."
The X Factor 2015 hits TV screens later this year on ITV.
