Stylish singer Gwen Stefani is helping winter ski enthusiasts look sexy on the slopes by expanding her fashion collection to include new sports gear.

The No Doubt frontwoman is partnering up with bosses at Burton Snowboards to design a range of cold climate clothes suitable for the snow for her L.A.M.B. label.

The street-style line, which will include items like houndstooth board pants and colourful parka coats, will launch this autumn (13).
