Justin Theroux welcomes first baby

Theroux, 54, and Bloom, 32, were married in a quiet ceremony in Tulum, Mexico, last year.

The news has been met with warm wishes from fans and fellow celebrities alike.

This is the first child for both the 'Leftovers' star and the 'Gilded Age' actress.

The couple has been relatively private about their relationship and the pregnancy until the baby's arrival.
