Selena Gomez has shared imagery from her first campaign with PUMA on social media.

The 25-year-old singer announced she had joined forces with the sportswear giant two months ago, but the star has now taken to her Instagram account to share photographs of her in the #DoYou advertorial, which sees her don the brand's new Phenom trainers.

And the star is ''so excited'' to finally share the pictures with her fans.

Alongside an image of the 'Kill Em With Kindness' hitmaker sporting a red velvet bodysuit, with grey shorts, the new footwear item and a black jumper, she wrote: ''Guys- I'm so excited to share my first campaign for the new @PUMAPhenom. #DoYou (sic).''

And the company have hinted they are honoured to have the vocalist represent them, as they have hailed her a ''triple threat.''

Puma has shared a string of photographs and video clips of Selena in the campaign on their photo-sharing site.

One image of the former 'Wizards of Waverley Place' star sitting in a car, read: '' A triple threat and AF. @selenagomez in Phenom, our most savage trainer yet. #DoYou (sic).''

And Puma have continued to describe Selena - who underwent a kidney transplant earlier this year, which was needed as a result of her battle with Lupus, a condition in which the body's immune system attacks healthy tissue - as a ''fearless'' female.

In a teaser clip of the advert, it read: '' Always in the spotlight. Always fearless. Presenting @selenagomez in our all new trainer that's engineered to slay every step of your day. Phenom drops tomorrow. #DoYou (sic).''

Selena is not the only star who has fronted campaigns with the fashion house, as fellow singer Rihanna - who was named the creative director of Puma in 2014 - has starred in a variety of commercials for the label, as well as 'Keeping Up With the Kardashians' star Kylie Jenner.
