Victoria Beckham makes her staff carry crystals to emit positive energy.

She said: "I'm really into crystals. I'm a real positive thinker. I believe in creative visualisation - the glass is always half full. I have no time for anything negative. I bought crystals for all my team, so they carry them too."

Victoria - also known as Posh Spice - isn't the only star to rely on the power of crystals; Adele, Madonna, Miranda Kerr and Sam Smith are also firm believers in their properties.

Sam splashed the cash on the holistic treatment at healers Spellbound Sky in Los Angeles when he was recovering from an operation on his vocal cords and also purchased a "love potion" to help him find a man.

Perhaps Victoria, 42, could hand out the stones to her and husband David Beckham's kids - Brooklyn, 17, Romeo, 14, Cruz, 11, and five-year-old Harper - who all have dreams of stardom.

Brooklyn has already tried his hand at photography and done some modelling, Romeo has starred in Burberry campaigns and is tipped to become a catwalk star, Cruz is a budding soccer player and also could be the next Justin Bieber after showcasing his singing talents and Harper will follow her mother into her fashion label.

Although Victoria loves everything about motherhood it is not without its embarrassing moments and the megastar was recently left red-faced at her kids' sports day.

Recalling the incident on 'Late Night With Seth Meyers', she said: "I was at sports day and I thought, 'It's the taking part that counts.' One of the mums said, 'We'll run at the back together.' Then she steamed ahead! She won and I was at the back."
