US girl group Fifth Harmony have partnered with peta2, PETA's youth division, to star in a new ad which asks people to 'Be An Angel For Animals'.

The singers follow in the footsteps of fellow musicians including Pink, Kid Ink and Cody Simpson, who have previously worked with the charity. Along with a print ad, they also feature in a video explaining how we can all 'earn our halos', from taking proper care of our dogs and cats, to choosing to attend animal-free circuses.
