Christina Aguilera - Christina Aguilera Enjoys Birthday Bowling With Adam Levine And Shelton

Christina Aguilera celebrated her 31st birthday with her pop pals Adam Levine and Blake Shelton at the weekend (17Dec11) by throwing a bowling party in Los Angeles.

The Beautiful hitmaker held a private bash for 50 friends and family at the Spare Room on Saturday, when she was joined by her fellow mentors on TV talent show The Voice, Maroon 5 frontman Levine and country star Shelton and his wife Miranda Lambert.

Guests, including Aguilera's boyfriend Matt Rutler, feasted on mini burgers and quesadillas and took to the bowling lanes, while others played board games like checkers, backgammon and Connect Four, according to UsMagazine.com.

And Levine had a ball at the party - he took to his Twitter.com blog after the night of fun to tease Shelton about his poor bowling skills.

He wrote, "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."

Aguilera turned 31 on Sunday (18Dec11).
