The latest celebrity vegans are power couple Jay Z and Beyonce. They are going "completely vegan" at least 22 days.
Other famous vegans include Carrie Underwood, Joan Jett, Monique Marvez, Henry Rollins, Pam Anderson, Casey Affleck, Ted Danson, Ed Begley, Jr., Jame Cromwell, Woody Harrelson, Al Gore and Anne Hathaway among many notables.
Jay Z wrote on his blog yesterday, as part of a "spiritual and physical cleanse." The famous couple started yesterday (the day before Jay's 44th birthday today) and will go through Christmas.
"There’s something spiritual to me about it being my 44th birthday and the serendipity behind the number of days in this challenge; 22 (2+2=4) coupled with the fact that the challenge ends on Christmas day," the rapper wrote. "It just feels right!"
