Nicki Minaj was displeased with the grass growing around her dressing room.

The musician performed at T in the Park Festival in Scotland last Sunday amongst fellow headliners Skrillex and Swedish House Mafia.

Nicki reportedly made audiences wait for over 50 minutes while she threw a fit over the grass surrounding her dressing room backstage.

The star was not prepared to walk on blades of grass that tall.

"Nicki went off on one about the grass around her area, saying it was far too long for her to walk on," a source told British newspaper The Sun.

"She threw a complete strop, pouting and pointing and asking someone to get a lawnmower to sort it out."

When she finally graced the stage, Nicki performed a 30-minute set as audiences booed all the way through.

Fellow headliner Jon McClure of Reverend and The Makers was appalled by her behaviour.

"You can (I suppose) be a d**k to your own crew, you're paying them. But everyone else? Not to mention the people out front. Ugh. (sic)," the musician tweeted.

"To clarify: Nicki Minaj has been a selfish s**thead to all the hard-working crew backstage at T. Pathetic. F**k off."

Nicki is said to have requested that someone tidy up the lawn at the Hackney Weekend festivities in London a couple of weeks ago.
