Rita joins the judging panel with fellow newbie Nick Grimshaw this year, sitting alongside Cheryl and head judge Simon Cowell.
Speaking to Free Radio's Adam Wilbourn, Rita said: "Being on a panel with another female is amazing, especially with Cheryl being such a girls girl, me and her really kicked it off straight away. I'm really happy that I just get to have a laugh with someone that gets it."
In fact, Rita thinks the panel this year is perfect.
"Obviously I have a good dear friend of mine already on there [Nick]," she continued. "And then Simon is just the overlooker! It's amazing to have four different personalities all over the place!"
The trailer for the new X Factor series was unveiled at the beginning of this month, showing Caroline Flack and Olly Murs in a lab while carrying out tests on the judges.
The very end of the trailer shows former judge Louis Walsh reappear as a cleaner.
