Rihanna flashes her taut stomach as she strips down to a sports bra for sultry new Puma campaign ad

She was named creative director of Puma in December last year.

But Rihanna's work for the sports brand is starting to gain momentum as he second sultry ad campaign was teased by the singer on Tuesday. 

Seen spinning around in front of a wind machine in a sports bra, the musician appears to be adding her own effortlessly cool edge to the German brand.

Rihanna - like sportsmen Usain Bolt and Mario Balotelli before her - took on the role as a brand ambassador late last year to oversea the womenswear branch.

WWD reported at the time that Rihanna would 'work with Puma to design and customise classic Puma styles as well as create new styles to add to the Puma product portfolio.'

She already seems to have added her own flair to the brand and is seen wearing the womenswear with a masculine touch.

Rihanna sports an oversized bomber and low-slung tracksuit bottoms, along with a backwards cap as she hints at her taut tummy in a sports bra.

The slogan reads, 'What are you training for?' as she spins around with her hair flicked out to represent the perfect mix between aspirational athletic shape and glamorous image.

Rihanna was practising what she preached on earlier that weeks, when she stepped out in a sporty green bomber after a late night on Friday.  

She was spotted leaving Milk Studios in Los Angeles, California, in a super-sized green jacket that swamped her shape.

Rihanna teamed the oversized cover-up with a pair of blue slim-fitting jeans which featured knee rips and turn-ups.

Look the bomb in a khaki jacket like Rihanna

We can always rely on Rihanna to go all bad-girl on us. Just look at her cool androgynous, grungy style here as she headed out in Los Angeles. Not just anyone could rock this look, you'd need serious style and attitude.

Rihanna harked back here to the original grunge jackets of the '90s, with authentic details such as the exaggerated shoulder and orange padded lining.

A bomber jacket is an essential part of any girl's wardrobe, and they happen to be huge news this season thanks to the likes of Saint Laurent, 3.1 Phillip Lim and Acne Studios. And although Rihanna's exact pick by Vetements is now sold out, you can head right to find alternative pieces by the brand at Matches Fashion. If it's a bomber jacket you're after though, head below for some fab copycats at the likes of Missguided and Topshop.

And if you want to make it seriously Ri-Ri-esque, opt for yours in a few sizes too big, oversized is always cool.

The B****h Better Have My Money songstress made sure not to go unnoticed as she slipped on a pair of black furry flat sandals which exposed her perfectly painted white toenails.

She sported a full face of evening-appropriate make-up with her short hair pinned into an elegant updo - presumably how she was styled for the shoot.

It certainly served to highlight her diverse style, since only days later she was unveiling of her new fragrance - RiRi - at Macy's department store in a pink lace prom dress.

In true Rihanna style, she opted for a show-stopping number which gave an affirmative nod to the Eighties.

Despite the tricky style, she managed to wear the bubblegum pink off-shoulder dress with sass.

The enormous puff-ball sleeves rather overwhelmed the singer's petite frame, but she did distract attention by flashing a lot of toned leg. 

She carried a silver box handbag on a chain and matched her towering Christian Louboutins to her thigh-skimming gown.
