Jennifer Lopez definitely expecting twins

It's been thought for a while that Jennifer Lopez, 38, might be pregnant with twins, and yesterday her father confirmed that J-Lo is doubly fertile. I thought she was pregnant with twins because she might have used IVF, which increases the likelihood of multiple births. But apparently twins run in the Lopez family.

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.

David Lopez says that he's bought special azabache bracelets for the babies, which are a Puerto Rican tradition. The bracelets, make out of black stone, are supposed to protect the babies from the evil eye. Though considering J-Lo's legendary diva behavior, I'm not sure the evil eye is the kids' biggest concern.

Lopez has been spotted buying baby supplies for both a boy and a girl, which greatly increases our chances that we may be subjected to a Marc Anthony look alike. I swear to God, if there is a God, he will give them at least 90% of J-Lo's genes. At least of the face genes. If one or both of those kids grow up to look like Marc Anthony, we'll pretty much be able to end the debate about the existence of God. In less frightening news, Star reports that the couple plan on naming the babies Max and Emme. Well it's no Pilot Inspektor (a la Jason Lee) but I suppose they'll do.
