Avril Lavigne is Sexy Sisterssick and tired of all the Nickelback jokes.

The singer, who is separated from Nickelback frontman Chad Kroeger, took to Twitter Thursday to call out Mark Zuckerberg for making a joke about the band.

"Either way, you're allowed your musical opinion however, your jab at Nickelback is in poor taste," Lavigne wrote.

She was apparently referring to a video the Facebook CEO posted earlier in the week demonstrating "Jarvis," the artificial intelligence system Zuckerberg created to control his home.

In the video Zuckerberg asks the AI, voiced by Morgan Freeman, to "play us some good Nickelback songs." To which it responds, "I'm sorry Mark, I'm afraid I can't do that."

"When you have a voice like yours, you may want to consider being more responsible with promoting bullying, especially considering what's going on in the world today."

Lavigne ended the note with the #SayNoToBullying hashtag and tagged several anti-bullying organizations as well. She also wants Zuck to know that #TheJokeIsOld and #NickelbackHasSoldOver50MillionAlbums.
