Anna Paquin revealed the name of her twin boy and girl, after keeping it a secret for almost a year.
Paquin and husband, Stephen Moyer, had their twins in September of 2012, and it has been revealed their names are Poppy and Charlie.
The couple were together last week for the season six premiere of "True Blood."
Moyer may have accidentally let the names slip after being asked about what his Father's Day plans were, and said his daughter Lily (from another relationship) was going to camp. He then said he would be "hanging out with Charlie and Poppy," reports US Magazine.
"I can't tell you because that would ruin the surprise," Paquin said when asked about her Father's Day plans for her husband according to US Magazine. "I don't know about [it being a] big surprise, but yes, there are plans."
The 30-year-old Canadian-born actress transitioned from child actress to a star as she got older.
She received her first huge break in 2000s "X-Men" and "Almost Famous," before landing the role of Sookie Stackhouse in "True Blood."
Moyer is an English film, television actor, and director best known for his role as Bill Compton in the vampire series.
HBO's vampire drama "True Blood" returned last night at 9 p.m. The first episode of the new season is called "Who Are You, Really?"
"It still has the flavor of 'True Blood,' as it always will, but it does have something -- a little spring in its step in an interesting way, I think," said Carrie Preston of "True Blood" regarding the new season to the Huffington Post.
"Everybody is finding the new chemistry between all of that and all those players. And of course, with 'True Blood,' there's always still a million new characters that are being introduced. I don't know how they keep that many balls in the air and continue to juggle, but they do."
