Dita Von Teese drinks a special green smoothie ''every day without fail'' to help keep her slim.

The 39-year-old burlesque dancer credits the ''glowing green'' drink to her enviable curvy figure, and admits she sometimes consumes it twice a day.

Dita - who has teamed up with Cointreau to design a new evening bag - exclusively told BANG Showbiz: ''Basically what I'd do is I'd have the green smoothie in the morning. Sometimes I'd have it for lunch, or from early morning until midday. Then I'd have a small lunch, vegetarian based, like a salad. Then I'll eat my normal dinner at night.''

Dita - who turns 40 at the end of this month - follows the recipe from a book called 'The Beauty Detox' by celebrity nutritionist Kimberly Snyder.

Although she admits she does like to treat herself, Dita says the book has taught her how to eat a nutritionally balanced diet.

She said: ''I've learned a lot about what foods are really good and really bad. There's a lot of myths going around.''

Despite working out on stage with her high energy performances, Dita - who is famed for her martini glass strip tease - says the smoothie is the main reason she is in such good shape.

She said ''I wouldn't really say burlesque is what keeps me in shape. The green smoothie, that's my number one secret.''

My Cointreau Evening bag designed by Cointreau ambassador Dita Von Teese will be available exclusively from Selfridges from 1st October, RRP £559.
