While Anna Paquin gave birth to twins nine months ago, she and husband Stephen Moyer have yet to reveal the babies' names until now.
Last night, True Blood season six premieres, and E! News caught Moyer slip the name of the kids.
When asked what was happening for Father's Day, he said they are planning on spending the day "hanging out with Charlie and Poppy."
Earlier in the week he told People magazine that he was keeping them out of the spotlight for a reason.
"They came much earlier than we were expecting. They were so fragile in the beginning. We are just trying to protect them," he said.
"We're trying to give them as much of a normal upbringing as you can in this town. They didn't choose to be actors - not yet! Who knows what they'll be? It's just a question of wanting to keep that private for them so they can choose."
