British singer Lily Rose Cooper has stepped away from running her own clothes store to concentrate on raising her children.

The pregnant star, formerly known as Lily Allen, launched Lucy in Disguise with her sister Sarah Owen at London's Covent Garden in 2010, but within months the business had relocated to a pop-up premises amid rumours it was struggling to make a profit.

The vintage clothes rental store reopened in a new venue in Soho in August last year (11) but the pop star, who is expecting her second child with husband Sam Cooper later this year (12), is no longer involved with the business.

She has handed the reins of the venture to Owen so she can concentrate on family life.

In a post on Twitter.com, Cooper writes, "It's not mine anymore. My sister took it over so I can concentrate on bubbas (babies)."
