YouTube singing sensation and Utah native Lexi Walker performed at Mitt Romney's annual Deer Valley retreat last week.

Walker, 12, posted a photo on Facebook with the former GOP presidential candidate, stating: "I got to perform for Mitt Romney at his summit in Park City! He is the nicest person!"

Since performing the national anthem at a Real Salt Lake game in May 2013, Walker's popularity has grown. In December, Walker starred in Alex Boye's cover of "Let It Go" and was asked to perform the song on "Good Morning America." The young artist also made an appearance on BYUTV's "Studio C" and has traveled to Japan to be a guest performer at a children's music competition.
