Wedding Crashers star Isla Fisher wearing a gray mini dress as she attended the premiere of her new film 'The Dictator' in London.

Isla Fisher and Sacha Baron Cohen have reportedly become parents for the second time.

The couple - who already have a two-year-old daughter, Olive, together - were spotted out in London on Friday (10.09.10), pushing a pram meant for a newborn baby while little Olive walked in between her parents.

A representative for the couple said they will not be commenting on the reports but it is thought the new addition arrived earlier this month.

Isla and Sacha are notoriously private when it comes to their family life and even refused to confirm Isla was pregnant again, despite her being pictured with a huge baby bump.
