As she hosted the bash at Vegas hotspot, Tao, on Saturday (26 July), Rita certainly made sure all eyes were on her with her very revealing outfit choice.
Stepping out in yet another all-in-one (last week Rita donned a skin-tight jumpsuit alongside Iggy Azalea), Rita oozed sex appeal in her latest leather version.
Looking super-hot, the 'Never Let You Down' singer dared to bare all as she wore a very revealing leather all-in-one catsuit featuring turned up sleeves and gold zip detailing.
Wearing her zip low to create a plunging neckline, Rita showed off her cleavage as she sizzled on the red carpet. She teamed her catsuit with a pair of studded black boots, multiple gold chains and a chunky gold bangle on her wrist.
Rita vamped up her biker-chick inspired ensemble with a statement red lip, heavy eyeliner and a sleek black manicure. She wore her long blonde locks tousled in loose curls, sweeping her fringe messily to the side.
Looking every inch the global superstar, Rita was clearly excited about hitting the legendary Nevada Strip.
She tweeted: "Tao tonight Vegas see you there!!! Come and say hello! We about to party!!"
And no doubt she did as Rita took to the stage to perform at the event.
Let's just hope she didn't work up too much of a sweat in all that leather!
