The 46-year-old actress, however, said she would not dismiss it if her nine-year-old twins Hazel and Phinnaeus or her six-year-old son Henry want to follow in on her footsteps, reported Hello magazine.
"You have to approach each child differently and each desire that they have different and it's brought me an enormous amount of joy, my job, so I wouldn't just dismiss it," Roberts said.
"But I think I would investigate it, especially if they were a child," she added.
