Both Katy Perry and Avril Lavigne have caught some flak for videos they both released this week.  

Avril released a video for her song, "Hello Kitty" and some people think it's offensive because of the way it shows Japanese "J-Pop" culture.  

Take a look and feel free to comment below:

Katy Perry released a trailer for her upcoming video for "Birthday," and she shows off her acting ability by playing the "world's worst birthday party entertainers."

Some people aren't happy about the Jewish emcee, for this joke:  "Did you hear about the rabbi who did free circumcisions?  He only did it for TIPS!"  

Check out the whole thing, and again, feel free to comment below on whether or not you were offended.
