Justin Timberlake could actually be bringing sexy back with the news that the singer has just signed a deal with the founders of J. Lindeberg to launch a range of womenswear, courtesy of a new sportswear line under his label William Rast. JT, along with his business partner Trace Ayala, have teamed up with Paris68, the Lindebergs' New York-based independent design consultancy. "I have always admired the modern designs and sophisticated aesthetics of Johan and Marcella Lindeberg," said Timberlake.

"I am really excited that we have the chance to develop these strong collections together and that my vision for a complete William Rast lifestyle brand is in the hands of two of my most favourite designers," he added.

Although William Rast already stocks a womens' jeans range, the label is still chiefly known for its menswear collections. The new womenswear range will incorporate a "sexy tomboy attitude," featuring intricately constructed T-shirts, tailored jackets, high-waisted skirts and fitted trousers.

The full range is expected to launch for autumn/winter '08-'09. The current William Rast line is available from Harvey Nichols.
