Her longtime on-and-off boyfriend Justin Bieber confirmed his engagement to girlfriend Hailey Baldwin on Monday.


But Selena Gomez looks carefree and gorgeous flaunting her taut abs in her latest Puma campaign.


The 25-year-old beauty was all smiles in the shot that drew attention to her incredibly toned physique.


She showed off a luminous and radiant complexion that was complete with a sweep of blush and a red lip.


Another shot saw Selena stun in a black and white striped pair of tights from the collection while she posed down on one knee.


Previously speaking about her ambassadorial role for the sneaker DEFY, the beauty said: 'To defy is to be brave’.


'Puma has captured this feeling perfectly with their new Defy training shoe. I remind myself daily the importance of defying the outside noise and being true to myself.’


'It's about pushing the envelope and not obeying any "expectations" placed on you by society.’


Selena's new campaign comes as her ex-boyfriend Justin Bieber announced his engagement to model Hailey Baldwin on Monday - after dating for a few weeks.
