Jay-Z eating like a pregnant woman

Well fair is only fair, right? More husbands should take cues from Hova.

Wonderwall reported Jay-Z is supporting his wife and future child by undertaking a pregnant woman's diet.

A source told Us Weekly that the 42-year-old and Beyonce are maintaining a “partially vegan diet."

"Jay's trying to be disciplined, and he needs the energy to support her,” the source said.

In an interview that aired on ABC’s 20/20, the 30-year-old “Best Thing I Never Had” singer talked to Katie Couric about how pregnancy has changed her eating habits.

"I've been really conscious [about food] because I've met so many people that say, 'My second baby, my third baby, I've learned my lesson,” she said.

"So I haven't been going crazy. I know it's important that I don't lose myself."

The healthier diet seems to be doing its job. The superstar has been seen at several of Jay-Z and Kanye West’s Watch the Throne concerts rapping along and dancing to the beats.

A source also told the magazine that the couple was "dancing up a storm" at a club at the Hollywood Roosevelt hotel Monday night.

"They were loved up and sweet together [and] partied until 4 a.m.!"

4 a.m.! That’s college student hardcore! Well guess it’s better they get it out of their systems now before they’re up all night changing diapers and feeding a crying baby.
