The power of three compels them.

It's been over 16 years since Charmed went off the air, but some of the original stars of the late-1990s supernatural drama are officially reuniting at this year's '90s Con.

Shannen Doherty, Holly Marie Combs, Rose McGowen, Brian Krause, Drew Fuller and Dorian Gregory will be reuniting in front of fans this March at the Connecticut Convention Center in Hartford, E! News can exclusively confirm.
