Miranda Kerr sprays perfume on the ends of her hair.

The 30-year-old supermodel has revealed her secret tip to smelling good constantly, saying she spritzes her favourite fragrance on the tips of her luscious locks.

Quizzed about her perfume spraying routine, she said: ''I like to spritz on the ends of my hair, and also on my clothing before I get dressed - just a little spritz on my clothing. It's a subtle way when you enter the room for people to feel your presence, but not be overwhelmed by it.''

The former Victoria's Secret beauty also admits she is a loyal fragrance wearer and tends not to change her signature scent once she's found one she likes.

Miranda told People.com: ''I like to keep it consistent. If I like a fragrance it just kind of becomes my signature. These days, if you find something that works, you might as well go with it.''

Miranda is the face of Escada's new perfume Joyful, which reminds her of her childhood and experimenting with different scents.

She explained: ''I remember playing with my mother's perfumes. She had quite a collection. On her dresser she had all the different perfumes. It was her thing. I didn't really get my own perfume until I was older, maybe in my teens. I remember using rose oils and sandalwood oil -- mixing those two together. I liked that balance of the fresh flowers with something that's very grounding. I think that's a nice mix of freshness and strength.''
