Whoever they may be!
The True Blood costars were spotted in Venice, Calif., today pushing a stroller containing the approximately 2-month-old babies whose names we don't know and whose genders remain a mystery.
Even when their arrival made news in September, Moyer's rep would only confirm that the couple had "recently welcomed twins into the world"!
We'll just go out on a limb and assume the babies are super-adorable and that mom and dad are loath to reveal any details because they like their privacy.
And not because their kids are vampires or anything like that.
Moyer also has a son, Billy, and daughter, Lilac, from previous relationships. (So, we should know his twins' names within the next 10 years or so.)
