Victoria Beckham carries crystals to bring her luck at her fashion shows.

The 40-year-old fashion designer has a number of superstitious rituals, including carrying Pink Quartz and Black Tourmaline precious stones while backstage at her catwalk shows.

Speaking to students at a Singapore art college, she said: ''If I told you my backstage rituals, and was honest you would think I was a little weird. I carry my crystals with me which some people might think as odd but it works for us.''

Victoria - who lives in London with her former soccer star husband David Beckham and their children Brooklyn, 15, Romeo, 12, Cruz, nine, and two-year-old Harper - runs her self-named fashion brand out of New York and admits that while she's enjoying her success, she still worries about bad omens.

She said: ''New York works and my team are happy there. We have a great set up there. We go to the same hotel. But I am quite superstitious. I don't walk underneath ladders. And if I see magpies I do the salute thing.''

According to an urban myth, magpies are said to bring bad luck and fate believers say that in order to reverse it you must salute the birds and wish them a ''good morning''.

Meanwhile, crystals - which are also carried by stars including Madonna, Katy Perry and Angelina Jolie - are believed to have a number of healing properties, although there's been no scientific evidence to support the claim.
