Well, we’re pleased to say that not only has it been revealed she gave birth to a little boy, the youngster’s name has also been unveiled.
According to TMZ, the couple, who are already parents to seven-year-old Olive and Elula, who is four, have named their son Montgomery Moses Brian Baron Cohen – that is some name for a little boy!
The 39-year-old and her actor husband Sacha Baron Cohen paid tribute to Isla's own dad, Brian, when naming their first son.
The couple were convinced it was a boy, with a source previously saying: "Isla's exhausted. Sacha helps, but she's been finding this pregnancy her toughest yet because her daughters are so active."
Congratulations again to the happy couple!
