Last week, Us Weekly confirmed that Isla Fisher and Sacha Baron Cohen had welcomed a newborn baby into the world. At the time, neither the sex nor the name of the baby had been revealed, but thanks to a copy of the birth certificate exclusively obtained by TMZ, we now have both.

The little baby boy is named Montgomery Moses Brian Baron Cohen, which certainly places him in the hallowed halls of unique celebrity baby names. Isla Fisher's father is named Brian, so that part is probably in honor of him, but the significance of Montgomery and Moses are a mystery for now. Either way, it's certainly a regal name fit for Hollywood royalty.

This is the couple's third child together, as they are already parents to daughters Olive, 7, and Elula, 4.
