Delta Goodrem has been told to dump boyfriend Brian McFadden by her mum.

Lea Goodrem told her daughter that the Irish singer is ruining her career and "holding her back", according to the Australian media.

Brian, who has been dating Delta for two years, wrote back to his partner's mother, hitting out at her accusations: "You don't know anything about my career or future. Delta is an intelligent, talented woman who is making decisions by herself. Be choice with your words in the future."
