Hamilton is a fan of art and has said that one of his favourite artists is Andy Warhol. Prior to the 2014 United States Grand Prix, Hamilton wore a gold-framed version of Warhol's "Cars, Mercedes-Benz 300 SL Coupe" painting hanging from a chain around his neck. From November 2007 to February 2015, Hamilton was in an on-and-off relationship with Nicole Scherzinger, the lead singer of the American girl group Pussycat Dolls. Hamilton owns two unrestored 1967 AC Cobras, one black and one red, and in February 2015, it was reported that he had purchased a Ferrari LaFerrari from "his rivals in Maranello".
