Roberts, 45, who takes care of her children - 10-year-old twins Hazel and Phinnaeus, 7-year-old son Henry with Daniel Moder, says juggling the roles of a homemaker and actor is already too much for her, reports eonline.com.
"Oh I won't (direct). I think any housewife will tell you that you're directing pretty much 24X7, so I'll stick to the in-house directing," Roberts said.
"It's too much for me. I love being an actor, I love being a homemaker and that's good for me," she added.
The Oscar winner has movies like "Pretty Woman", "Notting Hill" and "My Best Friend's Wedding" to her credit.
