She was the most-nominated artist of this year’s BRIT Awards.

But Dua Lipa has been accused of letting it go to her head, after reportedly ripping her name off her dressing room door and locking out well-wishers.

The 23-year-old – who won the BRIT for British Single on Wednesday night – was branded ‘a right diva’ for her alleged backstage antics, which comes just one week after she won her first Grammy.

A source told The Sun: ‘Dua’s dressing room was right next to the backstage beauty spa which meant plenty of people were heading past to get pampered before the show.

‘But she made it clear she didn’t want to be there after other guests kept heading in to say hi and wish her good luck.

‘In the end she slammed the door closed and ripped her name off it so nobody would realise she was there — people were saying she came across as a right diva.’

Representatives for Dua Lipa have been contacted by MailOnline for comment.

But despite her nominations glory, it was The 1975 and Calvin Harris who walked away the big winners on Wednesday, collecting two awards apiece.

Dua shared her solitary win with collaborator Calvin when their song One Kiss won Best Single.

On the night, Dua performed the chart-topping tune as part of a medley of Calvin’s big hits.

She impressed everyone with her performance, which concluded with a jaw-dropping yoga pose where her backing dancers lifted her leg up in the air.

It’s been a mᴀssive few weeks for Dua, who collected her first Grammy Award earlier this month for New Artist and Dance Recording.

She also experienced the ‘surreal’ moment that she unveiled her Madame Tussauds waxwork.

Wearing the same outfit as her performance at Glastonbury in 2017, the popstar has finally been immortalised among some of the world’s biggest stars.
