Taylor Swift angry with Jennifer Lopez?

London: Country star Taylor Swift is reportedly angry with Jennifer Lopez after the pop diva behaved rudely with her team

The 23-year-old `Love Story` hitmaker asked the pop diva to make a cameo at her concert in Los Angeles, but Lopez was apparently unpleasant to deal with, reported Showbizspy.

"Jennifer was extremely rude to some of Taylor`s closest friends backstage. Jennifer made it clear they shouldn`t look in her direction or speak to her," a source said.

"Now Jen is on Taylor`s bad list ? right along with her numerous exes. Taylor has decided she will never work with JLo again or even invite her to a performance," the source added.
