For her big, powerful performance at this year's ACM Awards, Lambert took to the stage in a sultry, black, Bao Tranchi sequined jumpsuit and sang a high energy rendition of her hit single "Little Red Wagon," that featured a noticeably changed lyric.
The song originally included the line, "I live in Oklahoma," where Lambert previously resided with Shelton during their marriage. However, on Sunday, Lambert forcefully belted out the line, "I got the hell out of Oklahoma."
Admittedly, Lambert has sung this particular lyrical update in the past, but never at an event where Shelton was also present.
It seems the celebrated songstress had no problem singing the modified version of her hit in front of her ex, who attended the star-studded show alongside his longtime girlfriend Gwen Stefani, with whom he struck up a relationship shortly after his divorce.
In fact, Lambert's medley seemed to include a number of songs about break-ups and lost loves. Along with "Little Red Wagon," she also performed "Mama’s Broken Heart" and "Kerosene."
However, there's some debate about whether or not Shelton and Stefani actually were in the house when Lambert performed. According to a report from InTouch, the couple left the MGM Grand Garden Arena during the commercial break before her number.
Whether the pair stuck around or not, fans on Twitter couldn't help but point out the subtle shade throwing, and viewers were divided between those who were here for it, and those who felt it was a "classless move" on her part.
Adding fuel to the fire, Kat Byus -- the wife of Blake Shelton's band leader and bass player, Rob Byus -- tweeted on Sunday, "More like kicked out. But honey - when did you ever speak or honor truth? #makesmyheartpound," which some took as a thinly veiled response to Lambert's Oklahoma jab.
🤮 more like kicked out. But honey - when did you ever speak or honor truth? #makesmyheartpound
Whether the changed lyric was actually meant as a jab at Shelton or not, Lambert's big night at the ACMs wasn't going to be overshadowed by a single moment. The songstress got a lot of love for her bold performance, and later got the opportunity to sing alongside country legend George Strait, where they delivered a touching rendition of his iconic classic, "Run."
