Beyoncé and her husband Jay-Z have big plans for 2014 -- they are reportedly ready to have their second child.

The hip-hop power couple is more than delighted with their adorable first child Blue Ivy Carter, who is actually turning two tomorrow, Jan. 7. The R&B diva and Brooklyn rapper have collaborated with their baby girl on individual tracks -- on "Blue" off Beyoncé's recently released self-titled visual album and Jay-Z's "Glory," setting the world record for Blue Ivy being the youngest person to appear in the Billboard Top 200.

Sources say the surprise release of "Beyoncé" has to do with Jay-Z's wish to have another child.

"The initial plan was for Beyoncé's album to drop in the New Year, but Jay-Z wants next year to be all about baby making," a source close to the couple claims. "The plan is to start trying just before Beyoncé's world tour ends in Lisbon."

In addition, the source says that the rapper is desperate for a second child to arrive on his birthday, since he is said to be keen for the new member of their family to be linked to the number four.

"Jay thinks four is their lucky number. He loves that the number runs through their lives. He wants their second baby to be conceived when he's 44," the source says.

The source also adds, "They think it'd be a good omen if their baby shared Jay's birthday [December 4] and they've even discussed arranging a C-section, if the timing's right."
