Fifth Harmony: 'We have the best fans in the world'

Fifth Harmony believe they have the best fans in the world.

The girl group's latest single 'Worth It' is their best performing track in the US yet.

When quizzed about the song's popularity at the Billboard Music Awards last night (May 17), Ally Brooke Hernandez said:

"Our fans are the best in the world. They support us.

"There's so much passion and love, so thank you guys."

When asked what their Harmonizers mean to them, Camila Cabello said:

"I think that the Harmonizers are especially wonderful because we have a very, very smart fanbase and they're also very passionate. So whenever they have any particular goal that they want us to achieve, they just kind of assemble and create. They're so intelligent about how they get us to that goal.

"I think we owe a lot of 'Worth It''s success to them as well, because they've been so on about requesting it on radio stations and streaming it. They've been incredible."
