December 18 is a big day for everyone on The Voice. It marks the Season 3 finale of the hit music competition and will be a two-hour extended finale, running from 9 - 11 p.m. ET on NBC.

But that’s not the only cause for celebration that Tuesday — it’s also coach Christina Aguilera’s 32nd birthday!

The pop diva is used to celebrating major milestones on her show. Just last night she performed her latest single, “Make the World Move,” with Cee Lo Green off her new album, Lotus, which was released on the same day.

Christina is happy to share her birthday with the Season 3 finale, as long as one of her finalists wins! Team Xtina’s Dez Duron and Sylvia Yacoub are still in the competition, although Brooklyn singer Adriana Louise got eliminated last night.

But for the first time this season, not every coach is guaranteed a spot in the live shows, with the bottom two contestants getting sent home each week regardless of team affiliation, so who knows what will happen!

Do you think a Team Xtina contestant will make it to the Final 4? Tell us below!
