Shiloh Jolie-Pitt raked in $4 million (which her parents donated to charity) and Jennifer Lopez's twins earned their famous mum a whopping $6 million when they appeared on the cover of People.
So, how much for reality star Kourtney Kardashian's new bub Penelope Scotland?
"She will be lucky if she gets $20,000 to $30,000 for the pictures," a magazine editor tells the Huffington Post.
"It's been a long time since paying to secure exclusive images of a celebrity baby guaranteed huge sales," the unnamed editor says.
"Kourtney's second child isn't such a big deal. If it were Kim's baby, it might be different, but with the exception of hardcore fans no one is waiting to see what Penelope looks like.
"The Kardashian craze has been over for some time now," the editor adds. "Now a picture of Tom and Katie is worth more."
The Kardashian craze is over? Hooray!
