Nicole Scherzinger finds long-distance relationships "really hard".
The former Pussycat Dolls singer – who has been dating Formula One driver Lewis Hamilton for the past three years – admitted it can be difficult conducting their romance across continents.
She explained: "I'm not gonna lie, it's really hard. But if it's worth it, you make it work. We just do our best by sending lots of emails and Skyping."
