Adele has been offered £20 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 £380,000 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."
Although Adele was forced to cancel one of her Wembley dates during the summer after damaging her vocal cords, Wynn bosses are not concerned about Adele potentially having to cancel any of her Vegas shows.
The insider explained: "Adele is a professional, and knows her own ability. And we are happy to be flexible in negotiations if it's needed in order to bring her on board."
Meanwhile, Adele revealed during her 'Adele Live' tour in March that she was planning to take an extended break from touring in order to focus on having another baby.
She said at the time: "I'll see ya later, I'll see ya on the other side. In a couple of years when I'll be back, you won't be able to get rid of me. I'm going to go and have a baby."
The 29-year-old singer already has four-year-old son Angelo with her husband Simon Konecki.
