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.
