Although just this week Lewis said he was single, he has been linked to model and Keeping Up With The Kardashians star Kendall in the past.
So the sight of Kendall and Lewis together in Manhattan on Thursday (10 September) certainly set plenty of tongues wagging.
They were seen together in May, when Kendall and friends including Gigi Hadid and Hailey Baldwin visited Monaco and watched Lewis compete in the Formula One Grand Prix.
So are they dating? Well, earlier this week Lewis told The Sun that he was single, but perfectly happy to be linked to gorgeous women.
He said: "I'm single. I'm not attached to anyone. I'm a free spirit so I'm just going in with no plans to settle down any time soon… I've been associated with some really beautiful women. I don't even mind as long as they're beautiful women."
Well, Kendall, 19, certainly is!
