The long wait is over for celebrity-baby fanatics: Jessica Simpson's daughter, Maxwell Drew Johnson, was born on Tuesday, and, if tabloid history is any guide, it won't be long until some lucky, free-spending magazine wins a bidding war to publish Maxwell's photo on its cover. How much will the snapshots be worth? Here, a by-the-numbers guide to Simpson's looming payday and the big business of baby's first magazine cover:

$14 million
Amount People and Britain's Hello! magazine paid for the exclusive U.S. and international rights, respectively, to the first photos of the Brangelina twins, Knox and Vivienne, in 2008. That still stands as the record price tag for celebrity baby pics. Angelina Jolie and Brad Pitt donated $11 million of it to charity.

Amount Simpson's management team already tried — but failed — to get for confirmation of her pregnancy, plus first baby photos. Although Simpson could still get that figure, the days of $14 million payouts for baby photos alone have past, celeb expert Cooper Lawrence tells E! Online. "That ship has sailed."

$14 million
Total haul Simpson could take home if she "plays her cards right," according to Fox News' Jo Piazza. How? She could pull in up to $5 million more a year by extending her Jessica Simpson Collection fashion line to include baby products and maternity wear. A TV show featuring Simpson, fiance Eric Johnson, and baby Maxwell could bring in $5 million more, and tweets plugging baby products could net Simpson $5,000 a shot, Piazza says.
