Miranda Lambert got emotional over a song she wrote with her ex-husband, Blake Shelton. It happened during her concert at the Hollywood Casino Amphitheatre in Illinois on Friday.

As ET Online reports, the 32-year-old country singer was in the middle of performing “Over You” when she started to choke up. Reportedly, she barely finished the song and relied heavily on her fans, who were also in tears.

“You went away

How dare you

I miss you

They say I’ll be okay

But I’m not going to ever get over you”

Miranda worked with Blake on the song, which was inspired by Shelton's brother, Richie. Richie died unexpectedly when Blake was only a teenager due to a car accident. The song became an instant hit and even earned the pair “Song Of The Year” from the 2012 Country Music Awards.

There is plenty of speculation surrounding what could have caused Miranda to tear up during her performance. Particularly, some netizens are taking it as proof of Miranda’s pregnancy and that she is not over her split with Blake.

According to Inquisitr, Miranda was called “emotionally unstable” and “hormonal” by some concert-goers. This, partnered with the already swirling rumours of her pregnancy, has many jumping to the conclusion that she and her new boyfriend Anderson East are expecting.

Miranda and Anderson, 28, publicly went out as a couple in January. The publication quotes a source close to the couple as saying that Anderson would make a great dad and that the two have plenty in common.

Despite this, there are still those that believe Miranda’s speculated pregnancy could just be the ultimate revenge on the judge of “The Voice.” That is, that Miranda’s blissful new relationship and the possibility of starting a family will be the ultimate retribution. After all, Blake supposedly wanted to start a family with Miranda before the two split in 2015.
