After 10 years together, country superstars Blake Shelton and Miranda Lambert are calling it quits. Subscribe now for an inside look into their shocking split, only in PEOPLE.
The sudden split of Miranda Lambert and Blake Shelton sent a shockwave through the hearts of their fans when they announced the end of their marriage Monday. But days earlier, fans might have seen an early warning sign at Lambert's Cheyenne Frontier Days concert in Wyoming.
When Lambert, 31, began to sing "The House That Built Me" she had to stop mid-performance to fight back tears.
"The last thing someone wants to do is cry in front of 19,000 people," she said, asking the crowd to help her finish singing the ballad.
Originally written for Shelton, 39, to record, he played the song for his then-fiancée while driving down the road one night. After hearing the lyrics she burst into tears, feeling an undeniable connection to the lyrics. "I took one look at her and just said, 'If you have this strong of a reaction to a song, you need to record it!' " Shelton told PEOPLE in 2011. Just like that, the song was hers.
The sentimental song – which earned the singer a Grammy and proved to be one of her biggest hits – has brought the singer to tears more than once. She also got emotional while performing at the Oklahoma Benefit Concert in 2013.
Members of the audience were taken back by Lambert's tearful moment in Wyoming.
"It really was upsetting. The song is so powerful to begin with," one concertgoer told PEOPLE. "[The crowd] just thought the song was super touching."
Also noticeably missing at the concert: her wedding band. The star took the stage sans ring to perform days before news of her divorce – which was both announced and finalized Monday – broke.
