Seahawks' Earl Thomas -- Yeah, I Got Married In a Crown ... Gets Topless at Reception (VIDEO)

Seattle Seahawks safety Earl Thomas got married like a king this weekend -- with an actual CROWN on his head ... and that wasn't even the best part!

Thomas and his high school sweetheart, Nina Heisser, tied the knot at Chateau Cocomar -- a MASSIVE palace-like estate in Houston.

The guest list included several Seahawks teammates -- including Russell Wilson who attended with his fiancee Ciara.

But things really got wild at the reception -- where Nina and her bridesmaids performed a dance to Rihanna's "Work" ... while Thomas took his shirt off and danced up on his bride.

There was also a special celebrity performance from R&B star Anthony Hamilton.
