Sienna Miller is often voted one of the world's most beautiful women but says there's only a couple of rituals she swears by.

Her best beauty tip is to use bronzer under the jaw-line. The stunning actress says it's important to add color below the chin as it adds "depth" to the face and helps it to blend in with the rest of the body.

She said: "Always bronze underneath your jaw-line - it contours the face and adds depth. The bridge of the nose, cheekbones and temples are also essential."

Sienna - who is famed for her laid-back style - also says it's important to wear a fragrance everyday as it helps to change your mood.

"Fragrances have a nostalgic element to them and are an important part of who you are and how you present yourself. They are a sensory weapon and have the power to change your mood. I like the citrus notes of the BOSS Orange fragrances - they are young, fresh and uplifting."
