Second baby for Aston Kutcher and Mila Kunis

But is it a boy or a girl?

Mila Kunis and Ashton Kutcher have become parents for the second time.

Melissa Raubvogel, a publicist for the actress, said Kunis had given birth without providing further details, including whether the baby was a boy or girl.

But dad Kutcher may have spilled the gender beans. In an October appearance on NBC's Today, he said the couple's two-year-old daughter Wyatt was pointing to her mother's belly and saying: "Baby brother."

Kunis and Kutcher, who were castmates in the sitcom That '70s Show, married in July 2015.
