X Factor beauty Nicole Scherzinger has shared her tips on how to look camera-ready while dealing with too little sleep and a hectic schedule.

In a new interview with Now magazine, the 'Poison' sensation explained that in order to look her best even when she's exhausted there are certain rules she abides by:

"I don't want to look exhausted on TV, so I get lots of sleep and drink lots of water too. I always wear a face cream that has a really high SPF in it to make sure that my face is protected and moisturised all day. Murad Perfecting day Cream is a life-saver. It restores my skin and can be used on its own as a moisturiser or as a primer for foundation."

Scherzinger also spoke about her love of fashion, adding that she favours designers who are bold with their style: "I love designers such as Dolce & Gabbana, Roberto Cavalli and Versace, who all design strong and sexy clothes, which is so my style."
