She dressed for comfort in jogging bottoms, trainers and a jersey top.
Jennifer and husband Ben Affleck only confirmed that she was expecting in August, when the actress was already five-months into the pregnancy.
She told reporters at the time: 'We're so excited, obviously... It's all good, it's great.'
The 36-year-old brunette has previously said she is 'so excited' about the new addition to the family, although she has not revealed the name or sex of the baby.
Her former Alias co-star Victor Garber says his close friend is happier than ever.
'She’s wonderful,' he says. 'She’s probably the best mother I’ve ever witnessed.'
And while Jennifer focuses on motherhood her husband is busy starring in highly-anticipated romantic comedy He's Just Not That Into You alongside Jennifer Aniston.
