Now that the new year detox season has begun, pop superstar Britney Spears has revealed that working out three times per week is key to keeping in shape. 

The 'Till The World Ends' singer explained that regular exercise helps to keep her trim and allows her to enjoy getting ready for red carpet events because she feels confident in her appearance:

"I'm very big on being healthy and working out three times a week. I go to bed early and get my beauty sleep. I also drink lots of water to keep my body hydrated. It takes me an hour-and-a-half to get ready for a red carpet event. I usually take a shower, wash my hair, blow my hair out and have a cup of coffee."

"Then I'll have my make-up artist come in and we'll decided on what we want to go for - a soft or sinister style! From there we look at the wardrobe and see if it makes sense, And then we through the process of getting ready, which is the funnest part."
