The Let You Love Me hit-maker was spotted partying the night away at exclusive London haunt Annabel’s for her sister Elena’s birthday.
Slipping in a figure-hugging lilac number, Rita looked glamorous as ever as she headed into the posh restaraunt.
Squeezing her assets into the outfit, the blonde beauty dared to flash her killer cleavage.
Posing for a snap at the dinner table, Rita gazed seductively into the camera as her chest spilled into view.
She cheekily captioned the shot: “Elena’s DURTY THIrTY starts now!! [sic]”
Putting her catwalk worthy pins on display, Rita’s dress featured a sheer skirt section meaning she as able to flash even more flesh while keeping her modesty firmly intact.
She completed her look with open-toe heels and wearing her locks in tight curls.
Rita’s more conservative outfit choice comes just weeks after her mum Vera Sahatçiu admitted she often tells the chart-topper off for her racy wardrobe choices.

Calvin Harris’ ex is just weeks away from finally releasing her second studio album.
Despite her global success, Rita hasn’t put out a record since her 2012 debut Ora.
Since then she’s had a string of personal and professional setbacks including a number of high profile failed romances and her infamous legal despite with Jay Z’s record label Roc Nation.
Speaking frankly about the experience, Rita told DIRECTV: “I think my fans can just expect tears, blood, sex, rock and roll, and the fulfilment of it finally happening!
“It’s been a journey! Sadly, it’s not really been positive.”
