The singer whistles and shouts to alert security about the Directioner

Harry Styles clearly really cares about his fans.

The singer’s older sister Gemma posted a touching YouTube video yesterday of the 20-year-old pausing midway through a One Direction gig in São Paulo, Brazil to help a fainting devotee.

Harry misses his parts in Don’t Forget Where You Belong in order to alert security to the ailing Directioner near the front of the crowd by shouting and whistling.

‘Good egg ,’ Gemma, 23, captioned the film, which was shot last Saturday.

1D finished the South American leg of their Where We Are tour on Sunday and are now on a two-week break before heading to Dublin, Ireland at the end of next week.

Harry told his Twitter followers on Monday that South America had been ‘absolutely incredible’ and that he’d ‘fallen in love with it’.

The curly-haired heartthrob’s followers think it’s lovely that he was so determined to help out the gig-goer in São Paulo.

‘Awh he is so caring and protective,’ wrote one on YouTube.

Another said: ‘He also threw a bottle of water at us in the concert in peru cause it was so packed we couldnt breathe. Hes an actual angel.’
