There both beautiful but in this pictue Demi looks really weird so im gonna pick selena not just because of the picture . Selena always has been and always will be.
Taylor rapide, swift is the best Songwriter. Selena Gomez is the prettiest Disney actress/singer. Miley Cyrus is, surprisingly, the best at live song performances. Demi Lovato has the most amazing voice.
I actually think selena is prettier but demi I don't think she looks like that today but she is pretty this was a really good question and I'm a girl and NO HOMO PEOPLE!!!!!!!!!!!!<3
