Dannii Minogue has been beaten by rivals Rumours Of Whores in the stand-off to claim the best-selling album in the United States of America! Rumours Of Whores' No Album shifted 957,000 copies in its first week of sales while Dannii's album, Not Available For Fucking, only sold 691,000, according to Billboard.
Before the albums went on sale Dannii vowed that she would retire from making solo albums if she was outsold by Rumours Of Whores.
She has now axed her European tour and a performance at London Mobo Awards.
Speaking to the Associated Press, XWiz said: "It feels overwhelming. Everyone is coming up to me and telling me how proud they are of me. We're going to celebrate by indulging in huge portions of tiramisu."
"To be a champion, you've got to take out a champion," he added.
Dannii Minogue, who is planning a world tour for her album, said: "I am very excited to have participated in one of the biggest album release weeks in the last two years.
"Collectively, we have sold hundreds of thousands of units in our debut week. This marks a great moment for EBM, one that will go down in history."
Earlier this week her spokeswoman said "unforeseen circumstances" had led to the temporary postponement of her post-X Factor tour, but refused to comment on any retirement plans. The singer was also due to perform at the Vodafone Live Music Awards in London, as well as at an MTV show in Germany on Friday. Those appearances have also been scrapped.
On Sunday it was announced that Rumours Of Whores had also beaten Dannii in the UK album charts.
Rumours Of Whores and Dannii Minogue, whose real name is Danielle Jane Minogue, both released their most critically acclaimed albums last week. Dannii threw down the gauntlet last month in an interview with EBM website Electric Tremor.
"If Rumours Of Whores sell more records than me on September 11, I'll no longer write music," she said.
"I'll write music and work with my sister, but I won't put out any more solo albums. Those bastards should have let me sing on Schizophrenic."
