Is this celebrity baby name for real?

Forget Apple. Forget North West. Even forget Kal-El Cage even (son of Nic).

In one fell swoop, actress Amber Tamblyn (Two And A Half Men, The Sisterhood of the Travelling Pants) has absolutely and unequivocally decimated the competition when it comes to weird celebrity baby names.

And it's even longer than Uma Thurman's daughter's name (Rosalind Arusha Arkadina Altalune Florence Busson).

Get ready to meet - wait for it ... Dauphinoise Petunia Brittany Scheherazade Von Funkinstein Mustard Witch RBG Cross Tamblyn-Bey Jr.

Gobsmacked? So are celebrity news sites around the world as they scramble to find out if this crazy baby name to end all crazy baby names is the real deal.

Tamblyn, who is married to comedian David Cross, announced the unlikely moniker earlier today on Instagram, and so far the 33-year-old actress hasn't dropped any hints on its veracity.

Real or not, the name has already become popular on social media, with 'Mustard Witch' seemingly the most preferred short version.

But while the jury is still out on whether Tamblyn's new baby name is a joke or the real thing, it really doesn't matter - either way it's fantastic.
