Health-conscious Spears works out three times a week

Britney Spears works out three times a week.

The 'Toxic' singer says exercising on a regular basis and eating healthily is very important to her as she wants to take good care of her body.

She said: "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."

The 30-year-old star also revealed how she loves getting ready for a glamorous night out.

She said: "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 decide 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. Then we go through the process of getting ready, which is the funnest part."
