Amid speculation that Beyoncé and Jay Z may be expecting their second child, sources claim to know the unconfirmed baby's sex.

In Touch revealed that the hip-hop power couple is having a baby boy, which reportedly made the Brooklyn rapper beyond happy.

"They're both elated," an "insider" said. "There's no question that [Jay Z] adores Blue, but he's felt an emptiness not having a little boy. When they found out the good news, it was like new life was injected into their marriage -- Jay is 150-percent invested now."

Before giving birth to now 3-year-old daughter Blue Ivy, Bey reportedly suffered from several miscarriages. The "Drunk in Love" duo, worrying that they might experience the same, have since been changing their lifestyle for the better.

For instance, Hov has reportedly cut back on his partying and work commitments so that he can make his family his number one priority. "

He even revamped his diet -- he jokes that he wants to be in shape so he can do dude things with his little boy, like shooting hoops," the insider claimed.

The "7/11" singer is also excited about welcoming her baby son, the source said.

"She had almost given up hope that she'd be able to give Jay the son he's always wanted," the insider added. "But now she's telling her closest friends and family members that 2015 is their fresh start."

The R&B diva also recently took to her Instagram account to share a cryptic photo that suggests she is pregnant. The image sees her buried in the sand, sporting what appears to be a baby bump on her stomach.

OK! magazine previously reported that Blue's sibling is on the way, claiming Beyoncé told her close friends at Kelly Rowland's baby shower in August.

"She told friends baby No. 2 is on the way!" an attendee said at the time.
