Comedian and daytime talk show host Ellen DeGeneres is receiving some backlash from fans after a joke about Katy Perry was taken as sexist. The star courted outrage on Wednesday after dedicating a tweet to the “Roar” singer on her birthday. “Happy birthday, @KatyPerry! It’s time to bring out the big balloons!” the star wrote over an image of her gawking, mouth agape, at Perry’s breasts.
