The 'Pretty Woman' star, who is married to cameraman Daniel Moder, said she found it tough when she tried to leave her kids, twins Hazel and Phinnaeus, to go back to work after they were born in 2004, reported Contactmusic.
"The first time I worked after I had Finn and Hazel was a play for four months. And they were a year-and-a-half old, and there was a little place in the theatre for them to play, and Paul Rudd's son was just younger than they were.
Roberts, 46, said she felt she had earned the right to take some time off with her kids because she had been working non-stop for so long.
"I had been working for 18 years when I had Hazel and Finn almost nine years ago. So I felt like I earned that time in my house and in my kitchen and in bed all day with these two little people. I felt that was my present to myself. I was fortunate to work a lot, and I worked hard, and I was very devoted to that, and then I earned this jewel box of a life that I felt completely entitled to.
