The now 34-year-old singer is celebrating her birthday TODAY (December 7). Happy happy birthday, Sara!!!

Before going on stage to sing her hit song “Brave,” Sara got the amazing news that she got nominated for two 2014 Grammy Awards – Album of the Year for The Blessed Unrest and Best Pop Solo Performance for the previously mentioned song. So well deserved!

“i seriously can’t stop shaking and now I have to go sing brave by myself at a NASCAR event which is awesome but can’t stop hyperventilating,” Sara tweeted. “I never in a billion million years thought I’d be nominated for Album of the Year. I’m litterally shaking. Best birthday ever. Woah.”
