Adele may become Las Vegas’ highest-paid resident, as one of the Strip’s finest hotels is preparing to offer her $500,000 a show. Bosses at the Wynn Hotel reportedly want to sign the diva for a 12-month residency. And if she agrees to the deal, just one performance a week in front of a Vegas audience would net her over $26 million. The superstar singer would also be able to rake in thousands more from VIP meet-and-greet packages, which can see wealthy fans fork over more than $26,000. A source at the five-star hotel — which boasts Michelin-star dining, an opulent casino and employs David Guetta as its in-house pool DJ — said she is now their number one target. Bosses are putting the finishing touches on their megabucks offer, which they plan to present to Adele’s representatives in January.
