Singer Nicole Scherzinger has said it is difficult being apart from her boyfriend, Lewis Hamilton. Being such a successful performer comes with a price the former Pussycat Doll has learned. The 'Right There' singer admits being on the road so much promoting her music makes her long-distance romance with boyfriend Hamilton, 26, tough. The 32-year-old said that she feels guilty being away from her man, especially when she can't support him during one of his races. She told British Glamour magazine: "I know that as much as I support him [Lewis], he sees other drivers who have their girls with them the whole time."
