Ever since the two megastars hooked up, there has been nothing but speculation about when they will break up. Time and time again, rumor has plagued their relationship, either referring to them disagreeing on their acting schedules or to their wedding plans.

Now, after the press said that Angelina Jolie wants to take her children and move to Africa or that she walked out on Brad because he wasn't home enough for their three children, rumor sparkles again as to the couple's next (unborn) child.

According to one of Brad's closest friends, the hunky actor wants a biological baby boy and he wants him as soon as possible. But Angelina is reported to be looking into adoption for a further enlargement of their unofficial family, so the two have been at each other's throats for weeks now, the insider claims.

'Brad wants another child, preferably a boy - but he wants a biological boy. He is adamant and wants her to get pregnant again right away', an insider told pagesix.com. The same source then added that Angelina wants to adopt a child, rather than have one naturally, so they cannot but disagree.

The two actors already have a natural baby girl, Shiloh, and two adopted children, Maddox and Zahara.
