Beyonce, Jay-Z offer lifetime concert tickets for fans who go vegan

Music superstars Beyonce and Jay-Z are offering fans a chance to win free tickets for life to their concerts in exchange for adopting a vegan diet for a month. The “Lemonade” singer announced the contest to her 123 million Instagram followers late on Wednesday in support of the Greenprint Project, which encourages people to reduce their environmental footprint by eating plant-based meals.

Beyonce pledged to eat plant-based breakfasts and go meatless on Mondays, while Jay-Z is promising to eat two plant-based meals a day.
