The 'Skyfall' hitmaker could earn at least $40 million for a long-term run similar to Britney Spears' upcoming shows, and the 'Rocket Man' legend giving her guidance.
An insider told The Sun on Sunday newspaper: ''Stacks of Las Vegas casinos are desperate to get Adele on billboards as a headliner in this town.
''The highest figure being touted is $40 million but it could be even higher. Elton's been a really good friend to her and they've been Skypeing to share parental advice.
''But he is a businessman too, and has been telling Adele Vegas residency could secure a really good future for her family.''
As well as helping support her fiancé Simon Konecki and their son 12-month-old son Angelo, a residency would draw comparisons to the likes of Elvis Presley and Rod Stewart, placing the 'Rolling in the Deep' singer in legendary company.
The source added: ''It would mean she would join the ranks of legends including Rod Stewart, Celine Dion and Elvis Presley who all made fortunes out of playing there.''
Corgan took to Instagram to confirm rumours of new Pumpkins material, saying the first songs could arrive as early as May.
