smoyer021011_01_230final.jpg Sooki and Bill are getting ready to welcome not one, but two little vampires!

Anna Paquin and Stephen Moyer are expecting twins, Us Weekly reports. The True Blood couple's co-star Sam Trammell - fellow father of twins - gave his well wishes to the soon-to-be parents. "I'm so excited for them. We sent them a special gift. It's so interesting that True Blood has become like, the 'twins' show."

Moyer has two children from a previous relationship, but this is the first child for Paquin, 29. So what's Trammell's best advice for raising multiples? "It's harder, having twins, but it's all we know. So we're trying to impart some decent wisdom. I told them to hold on tight," he adds.

Congrats to the happy pair!
