The couple announced they're expecting their second child this summer during a special segment on Extra. They're already parents to 2-year-old Gia Francesca.

"I am the happiest father in the world. We cannot wait to welcome baby Lopez number two into our lives," said the 39-year-old host of "The X Factor" and "Extra."

Gia also appeared on Extra Tuesday with a shirt that read: "Big sister Gia." The family also celebrated with a surprise baby shower.

Lopez wed Mazza last December in New Mexico.
