We think Sacha Baron-Cohen and wife Isla Fisher have had baby number two.

But the notoriously private pair won't confirm a name, the gender, if the baby is even born, or even if Isla was ever pregnant.

But she was either pregnant, or she had eaten a huge amount of tzimmus over Rosh Hashanah...

And seeing as the pair have now just been spotted pushing a pram on a stroll through north London with their two-year-old daughter Olive, it seems pretty safe to say there's another baby in the family - but is it a boy or a girl?

The pair have a £12.6m home in LA but could be staying with Sacha's parents in Hampstead Garden Suburb while on their London stroll?

If any mohelim get a call in the next few days from a Mr Baron-Cohen, maybe you could give us a tip off? And keep your eyes peeled for the birth anouncements in this week's JC.

Mazel Tov Sacha and Isla!
