Isla Fisher and Sacha Baron Cohen welcomed a baby boy [1] last week, and now his incredibly cute name has been revealed. The stars, who are already parents to daughters Olive and Elula, named their first son [2] Montgomery Moses Brian Baron Cohen, TMZ reports. News of the couple's pregnancy first broke back in October [3]. Since then, we've caught glimpses of Isla's bump during a Hawaiian family vacation in January [4] and her hilarious appearance at the Vanity Fair Oscars party [5] in February, where Jennifer Aniston [6] got up close and personal. Congratulations on the newest addition!
