Jay Z recently vowed to stick to a plant-based diet until Christmas Day.
And by the looks of it his wife Beyonce is supporting husband Jay Z in every way except for her wardrobe.
Whilst accompanying him to Native Foods in Westwood, Los Angeles, on Thursday for lunch, Beyonce wore camouflage jacket with fox fur collar.
The singer was wearing a £2,915 Christopher Kane wool-blend parka with real fur collar, which would have no doubt hit a bum note with any fellow Vegans dining at the restaurant.
Fashion faux pas aside, the mother-of-one looked effortlessly stylish as usual, teaming the coat with quilted tracksuit bottoms and platform ankle boots.
The Holy Grail hitmaker wrote on his Life and Times Blog on Tuesday: 'Psychologists have said it takes 21 days to make or break a habit. On the 22nd day, you've found the way.'
'On December 3, one day before my 44th birthday I will embark on a 22 Days challenge to go completely vegan, or as I prefer to call it, plant-based! This all began a few months back when a good friend and vegan challenged me to embrace a plant-based breakfast everyday. It was surprisingly easier on me than I thought.'
He added: 'It just feels right! So you can call it a spiritual and physical cleanse. I will post my progress. Any professional vegans out there that have any great food spots please help out! Please!
'I don't know what happens after Christmas. A semi-vegan, a full plant-based diet? Or just a spiritual and physical challenge? We'll see. P.S. B (Beyonce) is also joining me.'
