The trio of stars wowed on the red carpet, despite organisers' attempts to tone the ceremony down.
Rihanna and Katy Perry defied organisers' flesh ban when they attended the Grammy Awards in Los Angeles on Sunday (10th February).
In the days ahead of the event, it was reported that organisers had requested that stars held back from flashing their flesh at the 55th annual staging of the awards ceremony.
A leaked memo, obtained by Deadline, said: "Thong type costumes are problematic. Please avoid exposing bare fleshy under curves of the buttocks and buttock crack."
It added: "Bare sides or under curvature of the breasts is also problematic."
Despite the warning, the likes of Rihanna, Katy and Jennifer Lopez all attended this year's Grammys wearing a series of revealing outfits.
RiRi wowed on the red carpet in a sheer red gown, while Katy's revealing green dress was the talk of the night.
Jennifer Lopez appeared to have been inspired by Angelina Jolie as she walked the red carpet wearing a long black dress, which featured a waist high slit that revealed her right leg.
Meanwhile, Fun. were among the big winners of the night at the Grammy Awards 2013, picking up a total of two prizes including Best New Artist.
The trio made a comical speech as they pipped British singer Ed Sheeran to the Song Of The Year crown with 'We Are Young' and commented on how old they actually look.
Gotye's 2012 smash 'Somebody That I Used To Know' scooped a total of three awards at the Grammys for Record Of The Year, Best Alternative Music Album with 'Black Mirrors' and Best Pop Duo/Group Performance alongside Kimbra.
Following her huge triumph at the 2012 ceremony, Adele added another Grammy to her collection as she scooped Best Pop Solo Performance for 'Set Fire To The Rain'.
