Beyonce has offered her American fans the chance to win free tickets to see her and Jay-Z “for life”.
The catch? You have to commit to eating more vegan meals.
The offer – which Beyonce has shared with her 123 million Instagram followers – is for one fan only and has a 30-year time limit.
Beyonce is running the competition through the Greenprint Project – which highlights the positive effect veganism can have on the environment.
Fans can submit how many of their meals are plant-based and in return, get the chance to win 30 years worth of tickets.
Beyonce has long been associated with the vegan movement. The Vegan Society says she’s helped make a plant-based diet something to aim for.
She’s posted pictures of her food and encouraged fans to join her by opting for a plant-based diet.
