Are Little Mix and Fifth Harmony rivals?

It's natural for two girl bands formed on The X Factor to experience some friendly rivalry but not Little Mix and Fifth Harmony! In fact, Little Mix's Perrie Edwards says that she's really happy for the American all girl band! "I was really glad that they got as far as they did because usually it's really hard for girl groups," she tells J-14. "Until we won The X Factor, all the girl groups got booted out like the first week over here in the U.K., so I'm really happy for them. I think it's great that they got so far."
