The 32-year-old American Super Bass rapper left little to the imagination as she took to the stage virtually in her birthday suit.
She performed her biggest hits wearing a tiny black push-bra and a black thong beneath a see-through black stocking.
The Anaconda singer revealed even more when she turned her back to the audience.
From behind, her ample buttocks were fully visible under the transparent netting.
The eyeful was completed when she spread her legs wide.
She completed her look with some black ankle boots and a dash of pink lipstick.
All that happened to the delight of the crowd who could not stop screaming for more.
Now in its 44th year, the Roskilde Festival is the largest North European culture and music festival.
The week-long event ended Saturday with Minaj’s performance followed by Paul McCartney as the closing act later on in the night.
