One Direction star Harry Styles has laughed off rumours suggesting he's dating British model Cara Delevingne. The pop hunk was romantically linked to the catwalk beauty earlier this month (Sep13) and he fuelled reports of a blossoming romance by taking a front row seat at the Burberry show during London Fashion Week for Delevingne's runway strut on Monday (16Sep13). However, Taylor Swift's ex-boyfriend has dismissed the claims after he was quizzed about the relationship prior to the catwalk showcase. When asked by an MTV UK reporter, "Are you looking forward to seeing your girl Cara walking down the runway?", Styles quickly replied, "She's not my girl! I know what you're doing."
