According to reports, Nicki Minaj was booed by a crowd at Scotland's T In The Park festival over the weekend after showing up 50 minutes late to her scheduled performance, and then only performing for 30 minutes.

Nicki claimed she missed her scheduled flight after being held at the security checkpoint for too long.

She tweeted Monday that she had been "fondled" by a "very old" lady with an accent, and that's why she was late. Nicki also says TSA officials were taking pictures of her.

British singer Frank Turner, who also performed at T In The Park, didn't buy Nicki's excuse. He tweeted that she was a "selfish sh**head" and "pathetic" and told her to "f*ck off!"

The Sun reports that Minaj acted like a total diva backstage. She complained about the grass around her dressing room being too long, and demanded it to be cut.

A source says Nicki "went off about the grass" saying it was "far too long for her to walk on."

The source also said the YMCMB princess threw a tantrum, "pouting, and pointing, and asking someone to get a lawnmower" to cut the grass.

This is not the first time Nicki has acted this way. Two weekends ago, she got Radio 1 staff to cut the grass around her dressing room at the Hackney Weekend, The Sun reports.
