Us Weekly breaks the news that Angelina Jolie and Brad Pitt conceived Knox and Vivienne, their newborn twins, through in vitro fertilization so they could pop out babies factory.

The actress chose the procedure (which can cost around $12,000 a pop) so “she wouldn’t have to deal with the stress of trying to get pregnant,” the source tells Us. “She could just knock it out.”

They should just attach a conveyor belt starting from Angelina’s uterus and ending outside of her vagina. Things would go a lot quicker.
