Gwyneth Paltrow is launching her own collection of yoga wear.

The Iron Man star, who is a longtime yoga fan, has partnered with apparel company Beyond Yoga to design the range, which is being sold exclusively through Paltrow's lifestyle website Goop.com.

She says, "I've always wanted a one-shouldered exercise top and could never find one, so we've collaborated with Beyond Yoga (who make really chic, comfortable, perfect exercise gear) to make my dream top!"

She's not the only star creating studio clothing for yoga fans - hip-hop mogul Russell Simmons created his own line of goods, including clothes and mats, earlier this year.
