Julia Roberts, Pretty woman in Armani

Pretty Woman star Julia Roberts has designed a bracelet for Giorgio Armani to sell for World AIDS Day.

It is the first time the Italian designer has worked with another name on a product.

The leather bracelet in red or brown has a "Tree of Life" design and inside carries the initials J.R, Armani said.

"Julia has helped to create a beautiful accessory ... which will be a visible reminder of the part that we can all play in fighting AIDS in Africa," Armani said in a statement.

Armani, known for his classic, flowing clothes and subtle colors, has been a partner in the (PRODUCT) RED initiative to send funds from the sale of products to help the fight against AIDS since it started in 2006.

Oscar-winning actress Roberts has often worn Armani gowns to movie ceremonies and is a long-standing friend of the designer.
