Isla Fisher and Sacha Baron Cohen With Their Kids | Pictures

Isla Fisher and Sacha Baron Cohen spent yesterday afternoon at a kids' birthday party in the park with their daughters, Olive and Elula. Sacha and Isla chatted with other parents in Santa Monica while the girls had their faces painted. Isla has been spending time close to home with her family since premiering her dark comedy Bachelorette in NYC last month. She'll be back in front of the cameras soon, however, with a guest-starring role in season four of Arrested Development. The cult series began shooting its return episodes back in August. Meanwhile, Sacha is also gearing up for a new project. It was announced last week that he'll star in a Paramount film based on the real-life story of a Hong Kong billionaire who offered a reward for any man who could woo his daughter away from her lesbian partner.
