No Bad Blood Between JoBros and Taylor Swift?

The highly publicized split between Joe Jonas and Taylor Swift is still talked about today, thanks in part to Taylor not being able to keep her mouth shut about any of her past relationships. Well, it appears that Nick Jonas and his brother's ex are on good terms, or that's at least what he's trying to do. He covered one of the country star's most successful singles, "You Belong With Me", at a concert in Philadelphia on Saturday night (January 9). He also added a snippet of Demi Lovato's "Catch Me". Demi has also been romantically linked to Joe on several occasions and she is close friends with all three brothers.
