Is Sacha Baron Cohen's wife Isla Fisher expecting baby number two?

Sporting a dark baggy top, Isla Fisher – wife of Borat creator Sacha Baron Cohen – was out taking daughter Olive to playschool in Los Angeles on Tuesday.

Nothing unusual there, except for recent reports of what the T-shirt might be hiding.

The Australian actress was seen around West Hollywood at the weekend with a noticeable baby bump visible.

Isla and Sacha have not yet released any statement about a pregnancy, but the petite star's swollen stomach has fuelled speculation that two-year-old Olive might soon have a sibling.

The pair, who have been together since 2002, are notoriously protective about their private life.

They kept quiet about Olive's birth in 2007 and last month, got married in a secret Paris wedding well away from the cameras.

Only six guests were invited to the traditional Jewish ceremony, which was kept under wraps until the last moment.
