Lesson be learned, if you mess with Nickelback Avril Lavigne will come after you.
Facebook CEO, Mark Zuckerberg did a video demonstration earlier this week debuting Jarvis, a digital butler for smart homes. He then proceeded to make a joke about the band Nickelback.
"Play us some good Nickelback songs," he asked Jarvis. The robot butler then answered back, "I'm sorry Mark, I'm afraid I can't do that, there are no good Nickelback songs."
Unfortunately for the CEO, Lavigne did not find his joke funny in the slightest and took to Twitter to defend the band, who's lead singer Chad Kroeger is her ex-husband.
Zuckerberg has yet to respond to the singer's Twitter post.
Lavigne and Kroeger were married for two years and separated in September 2015. The couple still remains friendly to this day.
