Abbie Cornish wore Madonna's wedding rings in 'W.E.'.

The Australian actress felt "connected" to her director because of her willingness to use her own gems in the movie, including the bands she wore during her marriages to Sean Penn and Guy Ritchie.

Abbie told Style magazine: "She would bring a box of her own jewellery and handpick stuff for me to wear. Almost every piece I wear in this film was hers. Cartier and Bulgari earrings, necklaces, bracelets. She has an incredible collection.

"I wore both her wedding rings from her marriages to Sean Penn and Guy Ritchie. They were beautiful - white gold and diamonds. Every morning she'd bring them in and I'd put them on. It was nice to have that ritual and feel connected to her."

Meanwhile, Madonna has revealed she used to orchestrate group sing-a-longs on the set of the movie when they had downtime.

She said: "We would make up songs when we were waiting for the weather to change for outdoor shots.

"When it's pouring down with rain and you're shooting outside stuck in some grey, dirty shack waiting for the sun to come out, what else can you do?"
