‘A triple threat and hot AF’: Selena Gomez kicked off her new Puma partnership with a sultry photoshoot on Tuesday

‘Guys- I’m so excited to share my first campaign for the new @PUMA Phenom. #DoYou,’ she captioned a shot.

In it, the singer dons a retro red Puma tank top and grey workout shorts, showcasing her toned arms and legs in equal measure.

Her short black jacket never quite makes it onto her shoulders in any of the photos.

Her hair meanwhile is its more recogniseable shade of brunette, and not the dyed blonde she unveiled at the American Music Awards on Sunday, meaning the photos were taken before, or she has already ditched the new look.

On her feet are the heralded Phenoms, which fit like regular trainers but look like high-tops, thanks to the soft collar.

They are, according to the website, engineered for ‘optimal traction, stability, quick response and manoeuvrability, and look adorable,’ which are presumably all the things women need in training shoes.

‘A triple threat and [hot] AF. @selenagomez in Phenom, our most savage trainer yet. #DoYou,’ the sports brand boasted on its own instagram.
