Watch out Mason, Leo and Sparrow, because you're about to get some serious celebrity baby competition.

Hollywood is having a major baby boom and soon Mariah Carey, Natalie Portman, Pink and more will be welcoming new additions to their families.

And if Rosie Pope, the star of Bravo TV's new show Pregnant in Heels, has any say, these babies are going to have the most creative names in their A-list play groups.

Think "Twinkle Toes," "Carcass," and "Despair."

To find out what other hilarious names she came up with, watch her play 'Name That Baby' with Style & Beauty Director Andrea Lavinthal (above).

Pregnant in Heels airs Tuesdays at 10 p.m. (EST) on Bravo
