The 'Poison' hitmaker, who has been dating British racing driver Lewis Hamilton on and off since 2007, said it can sometimes be tough, reported Sun online.
"Every relationship has its things and you work it out. We made it last for four years so far, so it definitely makes things interesting and a challenge. "I wouldn't wish a long-distance relationship on anyone, Lewis would say the same.
But if it's worth it, you fight for it. We try to see each other as much as possible," she said. Scherzinger, 34, also denies anything unsavoury ever happened between her and Chris Brown, after they were apparently seen kissing. "Chris Brown and I are definitely just mates - I have known him since he was younger than 16. We were just talking," she added.
