Demi Lovato!!! Yup, never saw that one coming! Two generations of pop stars collided last night when Avril Instagrammed two cute pics of her and Demi with the caption:

 "Backstage Twinzies with my Girl Demi Lavato!"

The two pop princesses are sporting a similar hair style.. with half their head shaved and the other with long flowing locks. Both singers are confident and have strong personalities so maybe that made for a good connection!!

I'm all for music superstars being friends!
