Uber-bronzed Ariana Grande suffers a fake-tanning fail as she sports patchy and mismatching deep faux glow

It's not like Ariana Grande to make a misstep on her immaculate image.

But the pretty popstar seemed to have rushed her fake tanning regime on Wednesday night when she showed up to a beauty launch with finger marks on her shoulders and mismatching shades on her décolletage and face.

Ariana, 22, greeted her frenzied fan base with kisses as she arrived at Boots in London, slipping a pastel-coloured coat off her shoulders to expose her unsightly patchy tan.

Ariana, who was recently named the new face of MAC Cosmetics' Viva Glam line, had amped up the faux glow to complete a sassy evening look, featuring a super-plunging jumpsuit and megaheels. 

The carefully made up pop princess displayed an immaculate complexion on her cheeks, though it served as a contrast to the deep colour on her hands, arms and shoulders.

To set off the beauty look, Ariana wore bronze colour on her eyelids and a nude lipstick to highlight her pout.

Pack a punch in these Christian Louboutin platform pumps

It's becoming quite evident that Ariana Grande is a huge fan of platform pumps. And with her petite 5'0" frame, we can't say we blame her! The Love Me Harder singer wore a pair of sky high Christian Louboutin platforms to an appearance in London.

If you're not afraid of heights, then the Alta Vicky pumps might be for you. The suede stompers have a vertiginous 6.5 inch heel and a 2.5 inch chunky platform.

Adriana rocked hers with a black jumpsuit and a pastel hued coat but they would work just as well with a pair of distressed jeans or a little black dress.

As is characteristic of the US hitmaker - teetering on skyscraper heels and pouting with conviction - Ariana was all about the fans.

She made faces and blew kisses as the fanbase lined the streets outside the high street store and she gushed with admiration back at them.

Ariana is currently visiting the London-based Arianators as she promotes her latest single Focus in the United Kingdom.

Earlier on Wednesday she was pictured arriving at the BBC Radio 1 studios in central London to speak about the latest release.

The Focus singer cut an uncharacteristically effortless figure as she prioritised style over sexiness for her appearance on the popular station.  

Ariana 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.

The Focus songstress will perform at Capital's Jingle Bell Ball in December 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.
