The 'RIP' singer wore a very cheeky little black frock and, from the looks of it, absolutely NO underwear while out and about in Manhattan on Tuesday (23 June).
Rita's obviously been feeling a bit daring lately as the previous day she also stepped out in a very boob-baring outfit consisting of an unbuttoned to the waist shirt.
We can't WAIT to what she'll wear on X Factor! Something tells us it might be a little bit more demure than these outfits though…
Rita was announced as a new X Factor judge last week. She'll join close friend Nick Grimshaw on the panel alongside the returning Simon Cowell and Cheryl Fernandez-Versini.
She said last week: "I am excited to be coming back to The X Factor – I had a ball here in 2012. This is a journey I can't wait to embark on to find some talented singers. Its the new generation taking over. Booooom."
Rita served as a guest judge on the ninth series of X Factor in 2012, helping out at the London auditions. She went on to become a coach on the fourth series of The Voice UK before switching back to its ITV rival.
