Actor Chris Hemsworth and wife Elsa Pataky are not planning to have more children.

The actress gave birth to twin boys - Sasha and Tristan - five weeks ago. The couple already raise daughter India Hemsworth, who was born in May 2012.

`(We) do not plan to have more children, but you can never say never. With twins you have more work, and now I have to do it better,` showbizspy.com quoted her as saying.

After giving birth, Pataky waited for a couple of months to start her exercise regime.

`In my case, a specialised postpartum physiotherapist recommended not to work my abs until they were totally joined again,` she said.
