Jay-Z and Beyonce: Dieting Together!

Jay-Z is getting in touch with his feminine side these days.

The 42-year-old dad-to-be is supporting Beyonce's pregnancy any way he can - and that includes dieting with her! The duo are maintaining a "partially vegan diet" and that "Jay's trying to be disciplined, and he needs the energy to support her," Us says.

If that's even halfway true, it's pretty sweet.

Beyonce, 30, isn't going to let herself go just because she's expecting, even if she is eating for two these days. "I've been really conscious [about food]," she said.

"I've been trying my best not to lose control!"

Jay and Beyonce's commitment to healthy living seems to be paying off in more ways than one. A source they were dancing up a storm at Hollywood's Spare Room club: "They were loved up and sweet together [and] partied until 4 a.m.!"

Whatever "loved up" means, it sounds romantic. The next night, the paid hung out with Serena Williams, Kanye West and friends at Watch The Throne's afterparty.

Who said pregnancy would slow her down? Always great to hear about this awesome couple. They haven't revealed the sex of the baby, but it's totally a girl.
