Well, we eventually learned the twins were a boy and a girl. But how about the names? Today, we've got deets!

E! News got the scoop when they asked Stephen about his Father's Day plans last night at the Season 6 premiere of True Blood, in Hollywood, California. (There they are at the premiere, left). Since his 10-year-old daughter from a previous relationship, Lily, is heading to sleepover camp. Stephen said he'd be "hanging out with Charlie and Poppy."

So, there you have it: The twins' names are Charlie and Poppy. And Stephen's got a kid heading off to sleepover camp...on Father's Day? That's no fun!

Anyway, love these celeb baby names! What do you think? Tweet me @Cheaty or @Todaysparent.
