And, lo, she has come to pass, the most celebrated of celebrity babies: Shiloh Nouvel Jolie-Pitt.
Angelina Jolie gave birth to Shiloh, a girl, Saturday night in Namibia, a statement from Brad Pitt's publicist said.
There were no details on how mother, baby and Pitt were doing.
The girl is the third child for Jolie, 30, who previously adopted tots from Cambodia and Ethiopia, respectively. It is the first biological child for her and Pitt, 42, the Oscar-winning actress' offscreen costar.
Shiloh is a name of Hebrew origin meaning, "His gift," per thinkbabynames.com. It is also associated with an 1862 Civil War battle, and a Neil Diamond song about a desperately lonely childhood. (Diamond's imaginary friend, however, spelled his name "Shilo.")
Shiloh's future classmates at Hollywood Montessori potentially include: Suri (Tom Cruise-Katie Holmes); Zolten and Moxie CrimeFighter (Mr. and Mrs. Penn Jillette); and Moses and Apple (Gwyneth Paltrow-Chris Martin).
While Shiloh's parents have yet to marry, they are already entrenched in family life. In January, Jolie's two older children, Maddox and Zahara, formally added Pitt's surname to theirs. Pitt is in the process of becoming Maddox and Zahara's adoptive father.
Jolie and Pitt met on the set of their 2005 action hit, Mr. and Mrs. Smith. They've been an item since Pitt split with then-wife Jennifer Aniston in early 2005.
Though a Hollywood couple in the figurative sense, for the last several weeks, Jolie and Pitt have been a Namibian couple, holing up in that African republic to await the arrival of the baby. An ongoing Namibian radio station poll showed approval by a 52-48 margin Saturday that Jolie's birth day be declared a public holiday.
Jolie recently completed filming on the CIA saga The Good Shepherd, opposite Matt Damon and Robert De Niro. It was on the location set of that film that Jolie last January let slip that she was expecting.
Pitt is due to earn money for his growing family in Ocean's Thirteen, the latest heist in the Ocean's Eleven saga.
