Focus on me: Ariana Grande swapped her skimpy ensembles for something far more stylish as she was pictured arriving at the BBC Radio 1 studios in central London on Wednesday

Ariana, 22, slipped into a chic white jumpsuit which mostly concealed her lithe frame, aside from the plunging neckline which offered a glimpse of her pert assets.The chart star teamed the simple one-piece with a see-through mac coat which protected her from the autumnal downpours although she deliberately let it hang off her body for a high-fashion feel.

She heightened her petite figure with her favourite pair of two tone heels which perfectly co-ordinated with the rest of her outfit.

Ariana was professionally made up with fluttering fake lashes and bronze eyeshadow tones drawing attention to her bold brown eyes.

She appeared in high spirits despite the miserable day as she was greeted by a small crowd of admirers on arrival to the venue.

She made time to entertain the fans, briefly talking to them and blowing kisses as she made her way into the building.

Ariana’s career continues to go from strength to strength as not only has she recently been named the new face of MAC Cosmetics’ Viva Glam line but she also tops the bill at Capital’s Jingle Bell Ball in December.

The Focus songstress will perform at the annual event at London’s O2 alongside ex-boyfriend and former The Wanted singer Nathan Sykes as well as a handful of chart acts on December 5.

The pop pair dated for four months from August in 2013 before going their separate ways just before Christmas.

However, the former couple are still close, according to 22-year-old Nathan, anyhow.

When the question was put to him in a recent interview, he responded: ‘Yeah, of course. When some things don’t work out they don’t work out. Long distances and stuff like that. On different schedules and touring in different parts of the world. It’s like sometimes it doesn’t happen so easily.
