It has been reported that Beyoncé is finally pregnant after months of in vitro fertilization treatments and expecting a baby boy with husband Jay Z. 

"Even though he's barely showing, she's paranoid that someone will pick up on it, so she's hiding her stomach whenever she goes out," a source revealed to OK! Magazine, via Hollywood Life.

"They've gone through so much to get here that they don't want to jinx it by telling everyone before the three-month mark," the source continued.

Daily Mail recently pointed out the R&B diva has been strategically hiding her stomach area with several objects in public for the last three months.

Bey certainly fueled pregnancy rumors when she was photographed covering her belly with a large black leather tote in New York City on July 15.

Earlier in the week, the "7/11" singer was also spotted artfully shielding her midriff with her Apple laptop.

However, the source also claimed that the "Drunk in Love" duo eventually wants to make the great announcement in an extraordinary manner, involving first child Blue Ivy, since "they know how much she wants a little brother or sister."

"They've been trying for a while, and it was so hard when it wasn't happening. They both desperately wanted another child and feel so lucky," the source added. "But they definitely won't tell everyone with just a statement - that's not their vibe."

In Touch, via Hollywood Life, previously reported that the hip-hop power couple is "in the process of having a baby through a surrogate."

"They were trying for several months, but Beyoncé was having trouble," an insider said. "She was scared about another high-risk pregnancy, so surrogacy became the best decision for them."

The insider also claimed that the pair has found a woman to give birth to their second baby.

"They didn't want to take any more risks, so after all the ironclad legal documents were drawn up, it took them about two months to find the perfect woman to carry their child," the source added. "The surrogate is still in the early stages of the pregnancy so they have yet to announce it to the public."
