Ben Affleck is looking forward to being ''Mr. Mom''.

The 'Argo' actor-and-director will be spending a lot of time at home with his children, Violet, seven, Seraphina, four, and 13-month-old Samuel, while wife Jennifer Garner works on her new movie 'Draft Day', and he is looking forward to taking a break from work.

He said: ''I'm preparing myself to take on some more of the burden at home.

''[Jennifer's] got a couple of movies coming up, so it's going to be a little Mr. Mom action, and I'm going to get back in the ring and we're going to see if I still have it.''

As well as focusing on his dad duties, the 40-year-old actor has been told by wife Jennifer to work on his physique following his recent admission he has been spending his days eating ''ice cream on the couch'' since 'Argo' won Best Picture at the Oscars in February.

He told People magazine: ''Jennifer is going to work. And she told me to go to the gym.''

Ben recently admitted Jennifer is the ''boss'' in their household.

Discussing their shopping habits, he said: ''You have the wrong idea about who is the boss in our house. I just follow her around asking, 'How much? How much was that?' ''
