Julia Roberts trying for another set of twins

Julia Roberts must really be enjoying motherhood. The 38-year-old actress is said to be attempting to become pregnant with another set of twins. According to the National Enquirer, Roberts intends to undergo in vitro fertilization next month and hopes to be pregnant by 2007.

A friend of Roberts and her husband Danny Moder said, “Julia turned to preimplantation genetic diagnosis simply because it's been shown to reduce the risk of pregnancy loss in women who are older and who, like her, have had trouble conceiving in the past. It is a side benefit that [Danny and Julia] could choose whether the baby is a boy or a girl."
