Often surrounded by mud and likely to be very dirty festival-goers are often regarded as a laid-back bunch, probably because of the steady stream of alcohol they have throughout festival days. However, Wireless festivellers were left angry and confused on Sunday after US star Nicki Minaj was two hours late for her performance.

The Anaconda hit maker was supposed to be on stage at 7pm but didn’t appear until 9:30pm - cutting David Guetta’s set short as a result.

The American rapper and singer blamed traffic issues for her delay but, whatever the reason, fans weren’t too happy that it took the singer so long to get to the stage.

When she did arrive, she joined Guetta onstage - who had been playing for an hour - and they belted out their collaboration, Hey Mama.

Minaj then went on to wow the crowds with her other hits including Anaconda, Feeling Myself and Super Bass.

In addition to the time delay, the singer courted controversy with her outfit when she suffered a wardrobe malfunction during her energetic set.

While bouncing around Minaj’s bra slipped down and she gave her fans an eyeful of nipple. However, when she finally did notice her outfit slip, she seemed undeterred and continued to give a rousing performance for the fans who had waited so long to see her.
