Hugh Jackman writes, “there’s every chance that I will be a vegan by the time you read” his foreword to Brendan Brazier‘s “Thrive: The Vegan Nutrition Guide to Optimal Performance in Sports and Life.” Jackman credits the diet for helping him add 20 pounds of lean muscle for his “Wolverine” role in 2009. “I am no longer interested in the ‘at any costs’ part of the equation [when preparing for a role],” he wrote. But with the book due out Sept. 14, Jackman’s still not a vegan, confirms his rep. Some people just can’t part with eggs.
