T In The Park performers have revealed Nicki Minaj acted like a 'selfish s***head' backstage at this weekend's Scottish festival.

British artists Frank Turner and The Sleeping Souls revealed their disgust at Nicki Minaj's behaviour behind the scenes at T In The Park, taking to Twitter to speak of rudeness and aggressive security staff.

The artists, also performing at the Scottish festival this weekend, expressed their outrage at the antics of both the rapper and her crew at the Kinross event.

"You can (I suppose) be a dick to your own crew, you're paying them. But everyone else? Not to mention the people out front. Ugh." Tweeted Frank Turner - referencing the fact Minaj was nearly an hour late taking to the stage, giving fans at the event no explanation for her delay.

"To clarify: Nicki Minaj has been being a total selfish shithead to all the hardworking crew backstage at T. Pathetic. F*** off," added Turner.

The Sleeping Souls also revealed their experience of Minaj, revealing her staff treated backstage crew with a lack of respect.

"You know what? Nicki Minaj can just f*** right off," the band Tweeted. "I know nothing about her music but backstage her security guy just pushed a crew person off the path into the mud so she could walk past."

Nicki Minaj was 55 minutes late to perform on the NME stage at T In The Park this weekend. She returns to the UK later this year for a string of headline solo shows. For more information, visit Gigwise Gig Tickets.
