When he launched his AI assistant Jarvis, who is voiced by famous actor Morgan Freeman, earlier this week, Facebook boss Mark Zuckerberg shared a video demonstrating the new feature. In it, he tells the “digital butler” to play him some good songs from Nickelback. “I’m sorry Mark, I’m afraid I can’t do that… there are no good Nickelback songs,” promptly responded the AI at which Zuckerberg answered “Good, that was actually a test.”

This is the latest in a series of jokes that plagued the Canadian rock band over the years. But they did found a defender in singer and former teen idol Avril Lavigne of “Sk8ter Boi” and “Complicated” fame.

She posted on Twitter, Thursday afternoon, a passionate defense for Nickelback, calling the Facebook CEO’s joke in “poor taste” and that he “may want to be more careful with promoting bullying.”

Lavigne, who is the ex-wife of Nickelback’s frontman Chad Kroeger until their 2015 divorce, maintains a very good friendship with the band.

She mentioned several anti-bullying organizations in her tweet, including STOMP Out Bullying. No representative from any of the implicated party has taken to comment the issue.

Here is her exact tweet: “Dear Mark, many people use your products – some people love them and some people don’t. Either way, you’re allowed your musical opinion. However, your jab at Nickelback is in poor taste. When you have a voice like yours, you may want to consider being more responsible with promoting bullying, especially given what’s going on in the world today. #SayNoToBullying #TheJokeIsOld #NickelbackHasSoldOver50MillionAlbums xx, AL.”
