“Harry was smirking every time Cara came along the catwalk," an onlooker told The Mirror.

“He kept looking away to avoid putting her off, but you could definitely tell there was chemistry there - even from the audience.”

"She was great, she did a great job. She looked amazing," Styles said, before plating a kiss on the cheek of the leggy blonde, causing her to break into a giggle.

Harry Styles was first romantically linked to Cara Delevengne last month after the duo were seen leaving a party together.

They were reportedly introduced to each other by their mutual friend Nick Grimshaw.

“Cara and Harry get on like a house on fire. Cara’s a tomboy and has a lot of male friends and Harry’s a cheeky guy and their personalities clicked right from the get go," said a source, according to sofeminine.co.uk.

“They both insist there’s nothing more but friends think they would make a great power couple of the showbiz world if they got together.”
