Who knew! I'll be honest, I never thought to look online or research celebrities that share my faith. So to my pleasant surprise, it turns out that there a ton of celebrities that are openly Pagan/Wiccan.
Patrick Stewart (identifies as Gardnerian) was not too much a surprise, more like a confirmation to me.
She played one on Buffy the Vampire Slayer, but did you know she's pagan? Allison Hannigan has been said to believe in real life too.
