He tweeted: "I've been baking like a maniac ever since. And I'm vegan now (again). #StandUpToCancer #GBBO @BritishBakeOff."

The tweet, which gained over 3,000 likes, caught the attention of animal-rights organization PETA, who thanked Brand for 'choosing the vegan life'.

Ex-vegan

In 2011, Brand's now ex-wife, Katy Perry, tweeted: "Me & the Mr. just watched 'Forks Over Knives'. You can get it on Netflix!" To which Brand wrote: "I'm now vegan, goodbye eggs, hello Ellen."

Since then, Brand left the vegan movement and returned to consuming animal products.

'Conflicting opinions'

The recent news of his re-transition to veganism has caused speculation on social media, with people asking the star to clarify his status.

One person replied to his 2011 tweet, saying: "This was a while ago now, yet in 2014 you asked for help in becoming vegan (The Trews). What’s the situation now - I’m trying to put to bed some conflicting opinions on your vegan status."
