Taylor Swift thinks Demi Lovato's comments were "unnecessary".
The Cool for the Summer hitmaker caused a stir when she slammed the 26-year-old singer's squad for using her song Bad Blood to fuel her ongoing feud with fellow musician Katy Perry.
A source says that isn't the case, and thinks 24-year-old Demi is just jealous of her "tight group of women".
The source told E!: "Taylor has a tight group of women in her life that all have her and each others' back and sometimes people just want that.
"She thought it was unnecessary for her to make those comments. They both have never been really good friends."
