OHMYGOSSIP — Taylor Swift is angry with Jennifer Lopez. The 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.

“Jennifer was exteremely rude to some of Taylor’s closest friends backstage,” a source told Star magazine.

“Jennifer made it clear they shouldn’t look in her direction or speak to her.

“Now Jen is on Taylor’s bad list – right along with her numerous exes.  Taylor has decided she will never work with J.Lo again or even invite her to a performance.
