Scherzinger, 35, claimed she is a "tomboy" in real life and admitted to sleeping with her make-up on, reported Femalefirst.
"The secret is simple girls, you need to ditch the fizzy drinks. Plus, it has a lot to do with my heritage. I hate to say it but I usually go to bed without my make-up on. I am like to tomboy in that way. But I drink only water.
"I have never had a carbonated beverage - well, I supposed a beer, but Coke or 7up I have never had that. Just water really, lots and lots of water," she said.
"Last year I didn't know what I was getting myself into and when i get nervous I just throw everything into my work. I didn't have anyone visit. This year I had my friends and family come.
So for the first time I have walked out in London... It is just nice to take in the culture and take in the history... I also went to my first fish and chip shop.
