It’s a boy! Isla Fisher and Sacha Baron Cohen’s newest addition to their family is a baby boy, TMZ reports. According to the site, the couple have named their first son together Montgomery Moses Brian Baron Cohen. Brian is Isla’s father’s name.

Us Weekly exclusively confirmed the pair, who are already proud parents to two daughters Olive and Elula, welcomed their third child last week.

Fisher, who was active up until the day before giving birth, couldn’t be more excited to be a parent.

"Family is 100 percent my top priority. So I'm much more comfortable doing supporting roles right now. And often, they're the most interesting. You get to be a character actress,” the Now You See Me actress, who opted out of the sequel, told The Telegraph of prioritizing her family.
