George R. R. Martin -- Burn Them All and Blow them Out!!! (VIDEO)

George R. R. Martin got a big surprise -- or 2 -- on his 67th birthday.

Martin, whose birthday was Sunday, hit up the HBO Emmys after-party last night at the Pacific Design Center, where around the stroke of midnight his wife surprised him with a birthday cake, which we believe is an awesome berry cake from Sweet Lady Jane.

George already got his big gift earlier in the evening ... he won his first Emmy for "Game of Thrones" -- he's been nominated 5 times for the series as a co-executive producer for Outstanding Drama Series.
