Beyonce Instagram Diet PHOTO: Jay-Z Reveals His and Blue Ivy Carter Mom's Plan for Vegan Challenge as the Christmas Holiday Approaches, 'Tom Ford' Rapper and 'Standing in the Sun' Artist 'Cleanse'

It looks like Beyonce and Jay-Z are going to embark on a special journey together as the "Holy Grail" artist announced that the famous power couple will be working on a new joint project. The artists have pledged to take on a plant-based vegan diet for the next three weeks.

According to Us Weekly, Blue Ivy Carter's dad took to his website Life + Times to reveal the news.

The rapper wrote, "Psychologists have said it takes 21 days to make or break a habit. On the 22nd day, you've found the way.

"On December 3rd, 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" every day. It was surprisingly easier on me than I thought... Why now?"

He added, "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...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 ha. I don't know what happens after Christmas. A semi-vegan, a full plant-based diet? Or just a spiritual and physical challenge? "

Coming to the end of his explanation to fans he wrote, "We'll see... Best of luck and health!"

Jay-Z added, "P.S. B is also joining me."

The "Grown Woman" posted vegan meals on her Instagram account supporting her husband:
