Nicole Scherzinger and Lewis Hamilton have split after a four-year romance.
The X Factor judge and the Formula 1 driver have been dating since meeting at the 2007 European Music Awards but their careers frequently had them on different continents.
Scherzinger, the former Pussycat Doll, is Hollywood-based. Brit-born Hamilton makes his home in Switzerland.
"So for now it's over. They think this is what's best," a source told People.
