Miranda Lambert got emotional in concert just days before announcing her divorce from Blake Shelton, and a clip of the teary performance is now making the rounds.

"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 told People in 2011.

Lambert ended up turning the song into a big hit. It also went on to win a Grammy.

Lambert and Shelton released a joint statement Monday announcing their split after four years of marriage, saying, "This is not the future we envisioned. And it is with heavy hearts that we move forward separately. We are real people, with real lives, with real families, friends and colleagues. Therefore, we kindly ask for privacy and compassion concerning this very personal matter."

The power couple were together a while before getting married. They met in 2005 and exchanged vows in May 2011 in Texas.

Lambert, 31, and Shelton, 39, have been in the tabloid headlines for months, with reports about hitting a rocky point within their marriage. Both Shelton and Lambert opened up about the tabloids and the pressures of being in a high-profile relationship in a 2014 interview with CBS News.

The rumors continue to swirl, meanwhile, with a new TMZ report that speculates Shelton believed Lambert had been cheating on him, so he filed for divorce.
