Blake Shelton and wife Miranda Lambert were on hand to help Blake's The Voice co-star Christina Aguilera celebrate her 31st birthday with a bash in the 1920s-themed lounge Spare Room on Saturday (Dec. 17). The lounge is located in Los Angeles' Hotel Roosevelt.

Nearly 50 of Christina's family members and close friends, including The Voice co-star Adam Levine, Blake and Miranda, all bowled at the venue's two vintage bowling lanes and played games such as Connect Four, checkers and backgammon. They also dined on mini-sliders and quesadillas.

Adam summed up the night on Twitter, writing, "Happy birthday to @TheRealXtina! I'd also like to thank @blakeshelton for being a terrible bowler. @blakeshelton I had to take advantage of your drunken state. I think you Bowled a 56. Which is impressively bad. Good work."
