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:
