Singer Estelle has announced the launch of her independent music label, New London Records.

The 33-year-old British star has departed John Legend's Homeschool Records and Atlantic Records to start her own imprint in partnership with music management company BMG.

She has worked as a writer for BMG since 2003.

"This is a new and exciting move for me," the American Boy hitmaker said.

"BMG has been an awesome partner throughout my career, and with New London we plan to continue bridging the gap between soul, pop, London and New York - uniting them through music."

BMG executive president Richard Blackstone said of the collaboration: "Estelle has been a valued member of the BMG family as a writer for some time now.

"She is a deeply passionate artist gifted with a tremendous voice and has music running through her veins.

"We are thrilled that Estelle has expanded our relationship and entered into a new partnership with BMG Label Services to release her upcoming album."

Estelle cracked America with the Grammy-winning American Boy, which featured Kanye West and became the sixth best-selling single of 2008.

Her fourth studio album and follow-up to her 2012 LP All Of Me is scheduled for release in February 2014.
