Kate Hudson is collaborating with Chrome Hearts on a jewellery line.
And then what you do is you hold it over your stomach. And then if it moves in a circle, it's a girl and a boy goes back and forth.
The 'A Little Bit Of Heaven' actress is the first actress to partner with the company on a range, which will be called CH + KH and sees Kate team with Chrome Hearts founders and close friends, husband and wife tram Richard and Laurie Lynn Stark.
According to WWD, the collection - a one-off set for now - will be 18 and 22 carat gold bohemian pieces set with white diamonds, fresh water pearls and aquamarine, green tourmaline, peridot and citrine gemstones and will launch in late summer in selected Chrome Hearts stores.
Kate is currently expecting her first child with boyfriend, Muse rocker Matt Bellamy, and recently said although she does not know the sex of the baby, she thinks they will have a girl after doing a "pendulum test".
Kate - who also has a seven-year-old son, Ryder, from her marriage to Chris Robinson - said: "So here's the pendulum test. You take a piece of hair and you take a ring, and you string it through - this is very witchy of me!
