"I don't know if I can walk in a straight line that well," said Styles. "I might fumble around, so maybe not. Maybe I'll zig zag, or switch it up a little bit."
Styles, 19, was rumoured to be dating Delevigne, 21, after they were spotted together at several parties during London Fashion Week.
He turned out to watch Delivigne at the Burberry show where he was spotted sharing a joke with Sienna Miller and Paloma Faith on the front row of the show, but denied that he and Delevigne were an item.
"People talk about anything really, but we're just friends and stuff," he said. "She is a lovely girl."
