She recently confirmed her romance with rapper Big Sean.

And Ariana Grande managed to tear herself away from her boyfriend for a whirlwind visit to London, where she paid a visit to the BBC Radio 1 Studios on Monday morning ahead of her highly-anticipated Victoria's Secret show performance the next day.

The 21-year-old pop princess looked like she hadn't got the memo about the chilly English weather, dressing in a seriously skimpy outfit for her outing.

Dare to bare: Ariana Grande stepped out in an extremely revealing outfit during her visit to the BBC Radio 1 Studios in London on Monday morning

The pint-sized star looked incredible in a white pleated mini skirt and a matching lace crop top, which showed off her tiny waist and emphasised her tan.

Ariana didn't let on how cold she was, making a half-hearted attempt at keeping warm by holding a grey fur stole close to her chest.

She paired the look with a floral cat ear headband and a pair of white heels.

The Break Free singer is rarely spotted without her favourite half-up, half-down hairstyle, but she switched things up for her London visit.

Ariana wore her brunette locks down straight and pinned the front sections off her face.

The former Nickelodeon actress recently opened up about her blossoming romance with Big Sean.

Keeping cosy: Ariana clutched a grey fur stole close to her, but chose not to put it on for extra warmth

She told Now magazine: 'I like boys with a bad boy kind of style, but Sean's the best boy I've ever met. He's a sweetheart.'

The vocal powerhouse, who was previously seeing The Wanted's Nathan Sykes, has always been very coy about her love life.

'I'm not that open... I'm still a little shy about it. But I am very happy and very loved-up,' she added.

Quick exit: One of her assistants was carrying a warm coat, no doubt in order for Ariana to put on as soon as she got into the waiting car
