Julia Roberts dotes on her children

LOS ANGELES, May 22 (UPI) -- U.S. film superstar and mom Julia Roberts tells Oprah Winfrey that things can get chaotic with three kids in her house.

Roberts and her husband, cameraman Daniel Moder, have a boy and a girl, 5-year-old fraternal twins; and a 2-year-old son. ET Online! said.

In an interview with Oprah Winfrey set to air Monday, Roberts said of her kids: "They are really angelic and wondrous. (It's) so heavenly and kind and dear and just to have that -- the chaos that goes on in our house and then the quietude that goes on. ... My favorite thing is just watching them wake up and watching them realize the day come upon them. It's just -- I don't know. It's fascinating to me."

Roberts said when her youngest child, Henry, woke her up early he told her, "It's a beautiful day, mama," it made "5:30 a lot prettier."

ET said Roberts' new film, "Eat Pray Love," debuts Aug. 13.
