Welsh star Duffy has been hit with a lawsuit from her former business manager for $320,000 (£200,000).
Angela Becker has begun High Court proceedings in the U.K. over claims she is owed outstanding payments from the Mercy hitmaker.
Becker, who began managing the pop star last year (10), alleges their partnership was due to end after Duffy finished promoting her album Endlessly.
But in December (10), the 27 year old moved to terminate their agreement early, according to Britain's Mail on Sunday.
