Another day, another celeb taking jabs at Taylor Swift on Twitter. This week, it’s “sk8er boi” singer Avril Lavigne.

It all started when a Taylor Swift fan compared the way the “Bad Blood” singer interacts with her fans to the way other pop stars do. The fan’s post on Tumblr juxtaposed pictures Katy Perry, Kanye West, Britney Spears and Avril Lavigne looking bored and awkward with fans to ones of Taylor hugging her devotees.

Taylor Swift favorited the post.

Lavigne defended herself Twitter with a collage of pictures of her and fans getting cozy.

Taylor Swift has yet to respond on social media.
