Beyoncé and JAY-Z Challenge Fans to Go Vegan and Win Concert Tickets for Life

Beyoncé and JAY-Z are challenging fans to go vegan and win concert tickets for life.

Queen Bey took to Instagram on Wednesday (Jan. 30) to announce “The Greenprint Project Sweepstakes,” which encourages fans to start incorporating plant-based meals into their diet. Those who participate will be entered to win the ultimate prize–up to 30 years of free tickets to see Beyoncé and JAY-Z in concert.

“What is your Greenprint?” Beyoncé asked in her post.

Fans do not have to go completely vegan to be eligible to win. They can participate in “Meatless Mondays” or enjoy vegan substitutes such as “plant-based for breakfast.” More information can be found on thegreenprintproject.com.

The Carters previously touted the benefits of a vegan lifestyle in the introduction to Marco Borges’ cookbook The Greenprint: Plant-Based Diet, Best Body, Better World. “Having children has changed our lives more than anything else,” they wrote (via TIME). “We used to think of health as a diet — some worked for us, some didn’t. Once we looked at health as the truth, instead of a diet, it became a mission for us to share that truth and lifestyle with as many people as possible.”

Fans are stepping up to the challenge. See some of the reactions from social media below.
