In scenes to be shown on Saturday and Sunday, the Minogue sisters look as though they’re having the time of their lives auditioning Dannii’s six acts. They were filmed in a sumptuous suite at the five-star Atlantis Palm hotel in Dubai, where rooms start at £1,000 a night.

Kylie, 41, dazzles in an emerald green off-the-shoulder dress while brunette Dannii, 37, wears a floor-length patterned gown. The last 12 acts – three for each judge – will be revealed at the end of next Sunday’s show before the live rounds begin next month.
