The 22-year-old, who arrived in Malta for the European summer music festival, Isle of MTV, posted a series of snaps to her Instagram account, as she modelled outfits for fashion brand, Filles A Papa.
Showing off her model catwalk, Rita can be seen confidently flaunting her body and washboard stomach, while striking fierce poses towards the camera.
Rita, who is rumoured to be dating superstar DJ Calvin Harris, embraced the warm weather and view of the Mediterranean Sea, and told her followers, "Malta!!! I love it here!!"
The 'Shine Ya Light' singer wore a black crop vest top emblazoned with the words 'Tomboy', and it appears the name was rather fitting for the star, as she revealed that she is a 'tomboy for life'.
Captioning one snap, she said: "And POSE! VOGUE! #strikeapose #mtvmalta #Malta #Tomboyforlife #Tomboybaby #Tomboy."
Rita will be performing at Isle of MTV today alongside the likes of Rudimental and The Voice coach Jessie J, who also showed off her bikini body in Malta on a hotel balcony.
Speaking ahead of her performance, Rita told her fans: "Big kiss... I miss you. #mtvmalta it's going to be a HUGE party tomorrow!!! I can't wait to see you!!"
Rita has been busy touring these past few months, in particular jetting back and forth between LA and London. The touring life and constant jet lag does take its toll on the singer though, as she performed a spectacular intimate gig for fans in London this month, despite not having slept for 48 hours.
