A doorman at The Pullman has confirmed her Madgesty is in the building.
When asked if there was any truth to the rumour international pop star Madonna was staying there, he simply said "yes", though denied having seen her in the flesh.
The band is reportedly at Sky City, while crew members are also believed to be at the Pullman, where Madonna is most likely occupying a penthouse suite.

The singer is understood to have touched down in Auckland on Tuesday afternoon by private jet.
She's in town for her Rebel Heart tour at Auckland's Vector Arena on Saturday and Sunday.
Recent and unconfirmed fan sightings placed her in Ponsonby at Ben and Jerry's ice cream shop and St Pierre's Sushi.
When contacted about their supposed celebrity guest a St Pierre's employee said they had not noticed anything out of the ordinary, "we didn't realise she was even here," the woman said.
Chris Watts was one fan eagerly awaiting Madonna's arrival at Auckland Airport on Tuesday.
He was told by a staff member at Air Centre One she had arrived at a private facility at the main terminal.
As he was leaving, Mr Watts said he spotted two Range Rovers with blacked-out windows head towards the main airport terminal.
The same two vehicles were then spotted leaving the Pullman hotel later that day, Mr Watts claimed.
He said they were part of a convoy of seven cars with tinted windows he had seen at the Pullman - "no sightings of Madonna tho [sic]."
An Australian guest, who had been at the five star hotel for about a week, said on Wednesday there there had been an "infux of American tourists" overnight.
He had not noticed if there was extra security in the area, nor had he laid eyes on the entourage of vehicles.
There was no sign of anything unusual as a Herald reporter staked out the Hotel for about an hour today - aside from two ladies with interesting outfits and American accents, and a man in a full tracksuit - resembling a backup dancer.
When questioned, staff at nearby apartment complexes, businesses, and eateries the area shook their heads, saying they had not seen a thing.
