Things seem to be just fine between Beyoncé and Jay Z these days, as they have been traveling in Europe, following their successful "On the Run" joint tour in September. However, the latest reports claim that the R&B diva has ordered rapper husband to lose weight, even saying that she is not sexually attracted to him anymore.

According to OK! Magazine, Bey has asked Hov to "lose 20 pounds" immediately because she is unhappy with his current not-so-fit body figure and worried about his health.

"She's so over his size and thinks it's ridiculous that he doesn't take care of his health," a source said. "She's worried about his cholesterol, his blood pressure, everything, and wants him to lose weight urgently."

The source also claimed that the Brooklyn emcee is "very inactive," as he "spends hours in the studio or in his office" and is "not the type of performer to jump about dancing like [Beyoncé] does" at the couple's tour or his own concerts.

As a result, the "Flawless" singer has taken some serious actions to get the "Magna Carta Holy Grail" rapper back into shape, such as putting him on her vegan cleanse, although he "cheated all the way through it."

Moreover, not only has Beyoncé suggested Jay Z take some effective diet plans and fitness regimes, but "she's even told him he's turning her off sexually, just to get him motivated."

Last year, the Roc Nation boss went vegan during his "22 Days Challenge." He wrote on his Life + Times blog, "Psychologists have said it takes 21 days to make or break a habit. On the 22nd day, you've found the way. On Dec. 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' every day. It was surprisingly easier on me than I thought."

He added that the challenge was "a spiritual and physical cleanse." He pledged to post his progress and asked any "professional" vegans for restaurant tips.

"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."
