Brad Pitt and Angelina Jolie are finally ready to exchange vows, according to OK! Magazine. And it’s all because of their kids. Sources say their children have been teaming up against them in their campaign for a wedding. “First it was Maddox, who has begged his parents to tie the knot for years,” a source says. “Lately, Shiloh and Zahara have been chiming in, and Pax thinks it would just be the coolest thing ever to be a ring bearer.”
