The pair were both celebrating the birthday of stylist Kyle De Volle at the Bo Lang restaurant in London.
And, while Rita opted for a grungy ensemble that included a clawed collar, Kelly opted to show off her curvaceous figure in a body-skimming black pencil dress that featured pretty embellished shoulders.

Kelly finished with classy patent stilettos, while Rita donned fierce boots and skinny jeans.
