NICKI MINAJ was 40 minutes late on stage at Wireless Festival in London on Sunday night – but that was nothing compared to the carnage surrounding her today.

The rapper caused chaos after announcing a last-minute meet and greet on the hottest day of the year, before turning up FIVE HOURS late after the police had been called.

Fans had started queueing at 8am for the midday event but countless people fainted and were left sobbing outside the venue after temperatures reached a scorching 32 degrees.

More than 2,000 people turned out to Cafe Koko in Camden, North London, in the hope of catching a glimpse of the US star after she revealed plans for the event during an Instagram Live at midnight on Sunday.

But she was so late that the venue couldn’t accommodate her, meaning she was mobbed in the street. At one point she had a tense conversation with two officers in the road as police attempted to hold back the thousands of people hoping to see her.

She was trapped in her car for 30 minutes but eventually got out of the vehicle to greet fans. However, the situation became so dangerous as people clamoured to get near her that she got back into her car and waved through the sunroof as she left.

One fan who was there said: “I lost count of the amount of people I saw faint in the queue – it was horrific. There was a girl near me who was crying because she felt so exhausted in the heat and I saw medics carrying people away who had collapsed, but everyone was just really desperate to meet Nicki.

“The venue had been told she was going to be there at midday but it kept being pushed back. By 4.30pm the security started telling people that they didn’t think she would turn up at all.

“When she did arrive, all hell broke loose and people were running around and pushing past others to get near her. People put their health at risk and spent an entire day waiting to see her. If Nicki actually cared about her fans, she wouldn’t have done this.”

Nicki’s headline set at Wireless Festival in North London’s Finsbury Park – her only European show of the year – saw her wear three outfits including this yellow and pink bodysuit.

But it only lasted 40 minutes because of her late arrival and because of a strict curfew for the festival.

Later on she splashed the cash on a night out clubbing with model Winnie Harlow.

Nicki clearly has plenty of money for hair, make-up and clothes.

Perhaps she should put her Wireless pay cheque towards a watch so she is punctual for once.
