Another Biological Baby for Jolie and Pitt?

There seems to be no end in sight to Brad Pitt and Angelina Jolie's family ambitions. The celebrity couple already have four children in their brood, three of whom come from the far reaches of the globe. Rumors last week suggested that the pair were looking for yet another unfortunate child to take in, but now, a source close to the Jolie-Pitt camp claims that their goal is actually an addition of the biological variety. eFlux Media reveals that the couple are studying health books and researching fertility-enhancing methods in the hopes of conceiving another baby. The first child born to Jolie and Pitt was Shiloh Nouvel, now 14 months old.

The source said that Jolie and Pitt are acutely conscious of the difficulty for adopted children Maddox (5), Zahara Marley (2), and Pax Thien (3), who do not look as much like their parents as little Shiloh.

The source also said that the couple have decided that "the time is right to try for another baby," revealing as well that Pitt is hoping for a boy. The decision to have another child with Pitt is quite a turn-around for Jolie, who once said that she did not necessarily want to have a biological baby with Pitt. But apparently, Pitt's devotion as a father was enough to turn Jolie around.
