Adele has been offered £20 million (NZ$37 million) for a year-long residency in Las Vegas.
Bosses at The Wynn hotel are reportedly so keen to sign the star up that they have offered her NZ$720,000 per show.
A source told The Sun on Sunday: "The days of entertainers coming to retire at Vegas are a thing of the past.
"In the last few years, we have seen massive stars performing on the strip and every major hotel wants to say they have the biggest star as their resident. Caesars Palace had Mariah Carey, Planet Hollywood has Britney Spears, and we want Adele.
"Even at half a million dollars a show we are confident we would make a healthy return."
