After being surrounded by incessant divorce rumors for months, Beyoncé and Jay Z are reportedly expecting their second child.

A source revealed to OK magazine that the Brooklyn emcee has been quite protective of his wife lately -- the similar way he acted when the R&B diva was pregnant with their now 2-year-old daughter Blue Ivy.

"For the last month, Jay has been fiercely protective of her, just like he was when she was expecting Blue Ivy," the source said. "He's been doing everything he can to ensure that Bey is in a stress-free bubble."

"He's informed their entire entourage that they need to use relaxed voices, mellow lighting and listen to only soft music, and he's said that all of the food Beyoncé eats should be organic," the source continued. "He's really doing his best to make sure that she's as comfortable and healthy as possible."

The "Flawless" singer also gave up drinking alcohol: "At one point, she was ordered a glass of champagne backstage to celebrate the tour's success, but she politely declined and even rubbed her belly, maybe unconsciously. She hasn't had a sip of alcohol since."

"Beyoncé is a little superstitious, especially since she had a miscarriage before Blue," the source added. "This is exactly the way they acted last time she was pregnant: tight-lipped until they were ready to break the big news -- which they did in a huge way at the 2011 MTV VMAs!"

The "Drunk in Love" duo is hoping their marriage to be more than just their "business." "The truth is, they're both desperate to make things work," the source said. "Business has always been a part of their relationship. But for Bey, family is the most important thing, and the idea of breaking hers up is strictly a worst-case scenario."
