Lucky Caroline Flack! Harry Styles' sister: He's thoughtful and caring
The One Direction heartthrob has been romantically linked to Xtra Factor host Caroline since they kissed at a party in October - and Harry's sister Gemma has no problems with the 15-year age gap.
'If he's happy, we're happy,' says Gemma.
'We're always going to be supportive of each other, whatever happens in our lives.
'I guess we're quite liberal in that way.'
And Gemma reckons Harry, 17, won't be shy in making his intentions known.
'Harry's very thoughtful and caring,' she says.
'If he likes someone, he'll tell them. He won't hide how he's feeling.'
