The FRIENDS IN LOW PLACES singer, 43, and blonde beauty, 41, married in front of family and friends at their Oklahoma home.
The couple's publicist NANCY SELTZER says, "They said it is the perfect Christmas gift to each other and they couldn't be happier."
The country singers began dating in 2004 and became engaged in front of 7,000 fans at a California concert in May (05).
This will be the second marriage for Brooks, who was formally wed to SANDY MAHL (86-01), while Yearwood was previously married to CHRISTOPHER LANTHAM (87-91) and ROBERT REYNOLDS (94-99). Brooks has three daughters from his marriage to Mahl - TAYLOR MAYNE, AUGUST ANNA and ALLIE COLLEEN.
