Jay-Z looked almost unrecognisable when he took to the stage on Wednesday night for the opening night of his joint tour with Beyoncé – On the Run II. The rapper showcased his slim physique while performing in Cardiff, dressed in a white suit with co-ordinating trainers and a statement pendant around his neck, which read "Bling for love". Other outfits of the night included a navy jacket and matching trousers with a contrasting stripe running down the sides. Beyoncé also looked as stylish as ever, dressed in a number of statement ensembles, including a sheer metallic jacket over a bodysuit, which she teamed with knee-high heeled boots.

The couple went through many outfit changes throughout the evening

Although it is not known how Jay-Z lost weight, it could be that he decided to go back to following a vegan diet. Both he and Beyoncé famously made a lifestyle change at the end of 2013 when they decided to go vegan for 22 days, and both enjoyed the benefits of their diet. Jay-Z announced that he would be going vegan on his website at the time. He wrote: "On December 3rd, one day before my 44th birthday, I will embark on a 22 Days challenge to go completely vegan, or as I prefer to call it, plant-based!!" Beyoncé reportedly went on a vegan diet again in the follow up to her Coachella performance in April, following the arrival of her twins Rumi and Sir Carter in June 2017.
