Lily Allen sued by tour manager

British singer Lily Allen has been hit with legal papers by a former tour manager for allegedly breaking a contract.

Bosses at EC1 Music Agency have filed a lawsuit at London's High Court claiming they were working with the Smile hitmaker on a comeback tour which was due to kick off in 2013.

The trek was delayed when Allen fell pregnant with her second child, but she allegedly told them to continue working on tour plans for 2014 to 2015. However, shortly after venues were booked, Allen allegedly signed with firm Creative Artists Agency (CAA) to run the trek.

EC1 Music officials are seeking compensation for at least $170,000 from Allen for allegedly breaking their contract and to cover the costs of the work they had already done.

The singer's lawyers tell Britain's Mail on Sunday newspaper they "will be defending the matter vigorously".
