It has been reported by The Sun that Duffy has split from Jeanette Lee, her manager, after five years together.
The relationship had "run its course", the newspaper reported her spokesperson as saying.
Duffy was introduced to Rough Trade's Lee by ex-60ft Dolls man Richard Parfitt and Catatonia's Owen Powell after she had appeared on S4C's Wawffactor.
The singer has been much criticised in recent months for her advert for Coca Cola, which was lambasted this week by Blur's manager.
She is currently recording the follow-up to her amazingly successful debut, Rockferry.
