The 'Your Body' singer turned 32 on December 18, but it was a bittersweet occasion for Christina, whose last appearance as a judge on The Voice coincided with the special day.
According to Us Weekly, Christina's doting boyfriend Matt Rutler made sure to take the birthday girl's mind off her departure from the show, throwing her a surprise party.
When Christina arrived home, she was met by 20 of her closest friends and family members, including her five-year-old son Max, and celeb friends Nicole Richie and Blake Shelton.
"There were tons of balloons throughout the house.
Christina was completely surprised. She was very happy," Christina told the magazine.
"Everyone was very friendly and got along well. They had a great time."
Earlier this week, it was revealed that Christina will be honoured at the 2013 People's Choice Awards, where she will be recognised for her achievements in the music industry.
The prize will also celebrate Christina's ability to reach millions of fans around the globe and across genres.
The 'Candyman' singer is also nominated for Favourite Celebrity Judge' for her role on The Voice USA and will be performing at the ceremony in LA on January 9.
