The best Christmas presents are the unexpected ones. Blake Shelton and Miranda Lambert gave residents and visitors in the small Oklahoma town of Tishomingo a very unexpected early Christmas gift: a surprise concert.

The fellow country superstars--who are also husband and wife--presented their impromptu concert at Lambert's bed and breakfast in Tishomingo, the Ladysmith, on Dec. 19, CBS reported.

"Blake is singing at 5 pm," the Ladysmith shared on their Facebook a few hours before the concert. "Come drink on it! $5 cover. Doors open at 4:30 pm."

Lambert joined Shelton, and the 80 audience members--a packed house--were able to meet the two stars after the concert.

Although this is the first time Shelton and Lambert have performed at the Ladysmith, the songstress makes sure she is involved with every detail of the business, which opened earlier this year across from her own Pink Pistol gift shop, reports The Boot.

The country star spouses will enjoy some time together over the holidays before they kick into high gear in 2015. Shelton will return for Season 8 of 'The Voice' on Feb. 23, while Lambert will embark on her Certified Platinum Tour beginning on Jan. 15 in Evansville, Ind.
