Before 11-year-old Lexi Walker went out to sing the U.S. national anthem at the REAL vs. Vancouver soccer game, her dad bet she couldn't hit the high note in the song. We assume it was only a method of encouraging her. If it was, it certainly worked. Check out the young singer not just hit, but smash that note. You can see more of Lexi's talent on her YouTube channel, where she can be found performing everything from pop hits to classics and hymns. At only 11 years of age, she already has an established career. We look forward to hearing more from this talented tween.
