David Beckham designs H&M kids' underwear collection

David Beckham has expanded his underwear range for H&M by designing a children's collection.

The 38-year-old, who retired from football at the end of last season, has added t-shirts and vest tops to the collection.

According to the Daily Mail, the bodywear range targeted towards youngsters, which is designed to mirror the sportsman's spring adult collection, will not be available until next month, and prices are yet to be confirmed.

Beckham is also expected to announce the development of an MLS franchise, rumoured to be in Miami, in the future.
