It's been three weeks since Brangelina twins Knox Léon and Vivienne Marcheline were born -- now, the proud parents are opening up about life with their newest additions, and clearing up rumors that the babies were conceived via in vitro fertilization.
"If they had been conceived through IVF, we would have been happy to discuss it," Jolie reveals to People magazine. "But we have been fortunate never to have had fertility problems."
The A-listers -- together since 2005 -- have four older children who are eager to help with the new tots. "Shiloh calls them her babies. She and Z pick out clothes and help change and hold them," says Angie. "It's sweet -- they are little mommies."
