The couple performed songs from their debut album, It's About Us, including the ballad "Bumper Cars" and "Just Kids." The duo also sang A Great Big World's "Say Something," which impressed fans and the X Factor judges when they performed it on the Fox competition show last year.

"HAPPY NEW YEAR YA LITTLE CUTIES! We had an amazing year and an amazing night with some of our favorite people ever!!!!! Now go have fun!" the couple tweeted after the show.

Alex and Sierra also retweeted a fan who shared a photo of them at the concert along with the caption, “Still so happy I got to see my favorite people perform last night.”

Alex and Sierra will probably make other fans just as happy when they hit the road in February with singer-songwriter Andy Grammer and alternative rock band Paradise Fears. The couple revealed the news via Facebook in December writing that they are "beyond stoked."

"We used to wait ages in line at @andygrammer concerts to get front row & a chance to meet... & now we get to tour together. life is rad," the singers tweeted.
