Though it's not unusual to see the "Vice" singer tear up onstage from time to time, Friday's performance in Hartford, Connecticut, was especially heartfelt thanks to one very special homemade sign.
Lambert halted her performance of her 2009 hit, "The House That Built Me," after spotting a soldier's sign in the crowd. The message read, "3 combat tours... Your voice was the last thing I heard every night. Thank you."
Lambert had the sign brought up to the stage, where she displayed it for the whole audience to see. Not only was Lambert moved to tears, but a close-up camera showed the soldier in the audience crying, as well.
The 32-year-old country star attempted to finish out the song, but happily let the audience take over as she mouthed "I can't do it" and continued wiping tears from her face. "Sing the verse," she told the crowd. "I gotta get a drink!"
Later that weekend, Lambert was treated to another big surprise when an adorable 6-year-old fan asked for her hand in marriage.
"When he came to my meet and greet, he got down on one knee and he was such a gentleman," she announced before launching into her 2007 hit, "Gunpowder & Lead." "It may be my favorite proposal ever. But it made me think about this song, because girls, we deserve that. So that being said, thank you, Sebastian. I'm gonna leave you with a pretty little love song."
