Miranda Lambert Cried on Stage Days Before Secret Divorce from Blake Shelton

Miranda Lambert broke down during a performance on Saturday (July 18, 2015), and now we know the root of her emotional on stage cry: her impending divorce from Blake Shelton, which was officially finalized yesterday (July 21, 2015).

Lambert broke down in the middle of performing “The House That Built Me” during her concert at the Cheyenne Frontier Days Festival in Wyoming.

She told the crowd, “No one wants to cry in front of 19,000 people,” as she paused. “I think you know this song so will y’all sing it for me?”

Fans captured the moment:

Won’t take nothing but a memory, from the #housethatbuiltme #MirandaLambert ❤️

The song was originally written for Shelton, but after Lambert heard the lyrics for the first time, during which time they were engaged, she felt so connected to it she started crying. Shelton told People in 2011, “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!’ “

The song also earned Lambert her first Grammy award.

Lambert, 31, and Shelton, 39, have been plagued by breakup rumors ever since they wed in 2011. Many sources have differing reasons as to why the pair finally called in quits.

One source told Page Six it had to do with children and their conflicting schedules. “He is eager to have children, but she really enjoys not being tied down. I think they both were off on what the time frame would be.

“They are never together, and he was wanting them to move close to being together. She really loves her career and touring. She has the ability to go and record albums when she wants and to tour.”

TMZ, on the other hand, is reporting that Shelton filed for divorce because he believed Lambert cheated on him not once, but twice. Shelton first heard rumors that she hooked up with country singer Chris Young, who opened for her a couple years ago, and he “thought it was believable enough to make him suspicious of her.”

However, it wasn’t Young who was the “catalyst” for divorce, but the other man (who is not a country singer). TMZ says “He received certain information about Miranda and the other guy that elevated things in Blake’s head from rumor to fact.”

As for how Lambert is doing, a source tells People, “She’s doing the best she can and taking it day by day,” and that she’s “sad and trying to process everything.”

Shelton and Lambert met in 2005 after performing a duet at CMT’s 100 Greatest Duets Concert.
