Taylor Swift and Demi Lovato have had a falling out. Their relationship is reportedly strained by Demi’s recent romance with Taylor’s ex-boyfriend Joe Jonas of the Jonas Brothers. Demi and Joe star together in Camp Rock 2: The Final Jam and have been denying romance rumors since October, when they were spotted on a double date with Joe’s older brother Kevin Jonas and his fiancée Danielle Deleasa.

I hope Taylor and Demi can mend their relationship, despite the Joe Jonas drama! It’s sad for me to see girls falling out with each other over a guy. What do you think? Would you feel the same in a situation like this?
