Girl group Fifth Harmony recently unveiled their new single 'Sledgehammer' in the lead up to the release of their highly anticipated debut album 'Reflection', and one of the stars has thanked fans for being so enthusiastic about their new music. 

Speaking to a Fusion reporter at the Jingle Ball, member Camila Cabello revealed that she's so proud of how dedicated her fans have been: "The Harmonizers always go really, really hard for us and I'm really happy that they like it ('Sledgehammer')."

The beauty took to her official Twitter page in the early hours of this morning and told her followers that she can't get enough of one particular festive movie: "Is it socially acceptable to watch 'Elf' after Christmas? Because if it's not I'll probably......... DO IT ANYWAYS TURN UP BUDDY THE ELF."

FIfth Harmony, meanwhile, recently spoke exclusively to Pressparty about Christmas and their plans for New Year's resolutions. You can read the full interview here.
