Fifth Harmony's Camila Cabello has admitted she shed tears while watching Taylor Swift's new concert film.

The US star released a documentary of her recent 1989 tour via Apple Music on Sunday (December 20).

It includes concert footage, as well as some of Swift's big-name live collaborations.

It seems, however, that it all got a little too much for 'Worth It' star Cabello.

She wrote on Twitter on Sunday: "Currently watching @taylorswift13's 1989 world tour movie in the backseat of my car and crying at how magical it is."

Fifth Harmony meanwhile have begun work on their second album.

The group recently said it will be "less gimmicky" than their 2015 debut 'Reflection'.
