Singer Amy Winehouse has called off all gigs and other public appearances for the remainder of 2007, after her doctor advised her to take complete rest.
The troubled performer was reportedly treated in rehab this year and UK fans booed her during one shambolic concert.
She had been due to play at the BIC in Bournemouth later and the Cardiff International Arena on Wednesday.
Gigs were also planned in December in Dublin, Belfast, Manchester and London, and all tickets will now be refunded.
A statement issued by concert promoter Live Nation blamed "the rigours involved in touring and the intense emotional strain that Amy has been under in recent weeks" for the decision.
"My husband is everything to me and without him it's just not the same"
"In the interests of her health and wellbeing, Amy has been ordered to take complete rest and deal with her health issues," the statement added.
A spokeswoman for the company said there were no plans to reschedule the concerts and fans should return their tickets to the outlet where they purchased them.
Winehouse, 24, was quoted as saying: "I can't give it my all on stage without my Blake. I'm so sorry but I don't want to do the shows half-heartedly; I love singing.
"My husband is everything to me and without him it's just not the same."
This was a reference to Blake Fielder-Civil, who has been remanded in custody until 18 January, accused of assaulting a pub landlord last June.
He also faces a charge of perverting the course of justice.
Critical acclaim
Winehouse's behaviour has been in the headlines throughout this year.
Last month she was fined after being found with cannabis in a hotel in the Norwegian city of Bergen.
She called off a series of concerts and appearances after reportedly being treated for drug addiction.
The US leg of her tour in September was shelved while she continued to address problems with her health, and there had been hopes that this would be rearranged for 2008.
But the singer has also received critical acclaim for her current album Back to Black, containing hits such as Rehab and You Know I'm No Good.
This year she was named best female singer at the Brit Awards, and she received two prizes at the Music of Black Origin (Mobo) Awards in London.
