The rumors are true, confirmed by no less a source than her father: Jennifer Lopez is expecting twins.

And it isn't even a Lopez family first.

"Yes, twins," her dad David Lopez said in an interview on the Spanish-language show Escándalo TV, PEOPLE en Español reports. "The thing is in my family, my sister also had twins, so it's a hereditary thing."

For David Lopez, the news means double the excitement.

"I'm very proud. Jennifer has yearned to be a mother for many years," he said.

And he already has gifts ready for his 38-year-old daughter's babies.

"In Puerto Rico it's custom to buy an azabache [black stone] bracelet for babies to protect them from the evil eye, it's part of our culture," he said.

As she became noticeably pregnant, J-Lo finally announced last November that she and Marc Anthony were expecting.
