The Masked Singer panellist was working on a campaign for Madonna’s clothing line when she made her get on the floor and kneel.
Recalling the story during an appearance on The Tonight Show Starring Jimmy Fallon, she revealed how the Queen Of Pop was trying to find her best light.
“I had an amazing moment with her, very awkward but also very unbelievable,” Rita said. “She really just made me find my light and by doing that we had to kneel on the floor.
“And I thought it was Like A Prayer in real life that was happening to me. I mean I had to go and breathe in the bathroom. This was earlier in my career. I was doing a campaign for her clothing line and so then she came to meet me and I loved it and I just couldn’t breathe.
“And then she was like ‘this is not my light, let’s get down’. I thought, ‘what? What’s happening?’ And so we did.”
Rita became the face of Madonna’s Material Girl fashion line in 2013, following in the footsteps of Georgia May Jagger, Taylor Momsen and Kelly Osbourne.
The pair developed a close working relationship with Rita even performing with the pop icon during her Rebel Heart tour in 2015.
She also made a cameo appearance in Madge’s video for single Bitch I’m Madonna the same year.
