The 'RIP' singer, 23, dressed as a cheeky Catwoman when she attended a fancy dress party on Friday night (28 March) with Sir Philip Green's daughter and fellow famous pal, Sugababes star Keisha Buchanan.
Game for a laugh Rita was the only one who embraced the super hero theme at Chakana nightclub, however, and looked hot as hell in a wet-look all-in-one - meow!
It was a busy night in Mayfair for the Kosovo-born pop star as she changed outfit not once, but twice!
Earlier in the evening, Rita arrived at China Tang restaurant at The Dorchester Hotel in red leather trousers with a matching colour coat.
After enjoying dinner with Chloe, Rita turned into her favourite superhero to party hard before finally ending up in cocktail bar Le Baron until 4am.
But we think we prefer Rita's more feminine look earlier on in the day, when she wore a pretty black and white dress with the word 'backbone' written on it.
She wore the outfit on a photo shoot in Hackney.
The singer has been busy promoting her upcoming single 'I Will Never Let You Down', which is released on Monday 31 March.
