Dua Lipa with her old teacher Rob

POP sensation Dua Lipa stunned children when she returned to her former primary school classroom in a BBC Radio One stunt.

The mega star met her former Year 6 teacher Rob, now the head at her old state school in Hampstead.

For Greg James’s breakfast show, she surprised a class which had been set up to audition for a part she missed out on in the school play when she was 10.

“I wanted the lead part in the school play – I didn’t get it,” said the New Rules singer of the role in Anthony Horowitz’s Groosham Grange.

Dua Lipa, who opened The Brit Awards ceremony last week, went to Parliament Hill School after leaving her old primary school in Hampstead in 2006.

The headteacher asked for the school not to be named because of concerns that super fans – the “dualites” – might start grouping at the gates and disrupting life for children and parents.

He said: “I remember Dua from when she was 10. She was a lovely kid. It was never a surprise she has done well. She was alway confident. She is a brand now. But there were flashes of time when I saw the child was still there. She was genuine. It was really exciting for her too. We are really pleased and proud of her.

“I just want all my pupils to be happy. It brings me so much happiness to hear stories of our kids who are doing well and still friends with each other. It’s lovely. When you leave us. You disappear into secondary and hopefully all goes well. It doesn’t matter if they are celebrity, what matters is that they’ve done well in life and they are happy.”

Ms Lipa, 28, admitted she had been nervous before her “audition” back in the school classroom.
