More than two years after their divorce, Blake Shelton and Miranda Lambert are back at war. The unlikely source of their latest strife? Garth Brooks’ lip-synced performance at the Country Music Association Awards on Nov. 8.

The first shot was fired by Miranda’s boyfriend, Anderson East, 29, in a Nov. 9 Instagram post. When he wrote that the 55-year-old country legend’s decision not to sing live “truly offends me,” Miranda agreed. “High five on this babe,” the singer, 34, commented. “If you can’t sing then don’t. It’s better to be honest than to pretend. I think it’s bulls–t.”

Blake, 41, just couldn’t let that diss stand. “Hey @garthbrooks,” he tweeted the next day. “I still love you. #hero #respect.” Blake wasn’t the only one supporting the singer. Many Garth fans answered back Anderson’s tweet. “Who are you? You haven’t earned the right to have an opinion about this… Have some respect. You sound foolish,” one person commented.

After Garth won Entertainer of the Year at the CMAs earlier this week, the singer openly confessed he did lip-sync during his performance. “We’re in the middle of 12 shows in 10 days. Not 10 shows in 12 days, 12 shows in 10 days. We did a game-time call on whether to sing the track or lip-sync and decided to lip-sync. The voice just isn’t there anymore, and you want to represent country music as best you can,” he said backstage, according to People.

Blake, Miranda: Stop. Don’t waste the bad blood on social media posts — start writing those country diss tracks!
