Madonna's Tour by the Numbers: 4 Kids, 8 Humidifiers, 3 Traveling Gyms and More Surprising Revelations

The Queen of Pop is going all out for her Celebration Tour.

After postponing the kickoff of her highly anticipated string of shows earlier this year, Madonna, 65, is taking London by storm this weekend with six sold-out performances at the O2 Arena.

According to a press release, the superstar will be joined onstage by four of her children — likely David Banda, 18, who's often danced in her shows, Mercy, 17, and twins Stella and Estere, 11 — when she takes the stage to perform 40-plus songs.

The show, which sees Madonna reuniting with longtime collaborators Stuart Price and Jamie King, is expected to cover four decades of her career, which got its start in New York City.

Paying homage to her early days, the singer's stages will be split into Uptown, Downtown, Midtown, East and West "grids."

Known for her iconic fashion, the star will be wearing 17 looks inspired by her archived costumes — and 25 of her 200-plus traveling crew will be from the costume department alone.

According to the release, she will be traveling with three mobile gyms, eight humidifiers in her dressing room and three physical therapists for the run of her shows.

Last month, a source told PEOPLE exclusively Madonna was focused on her tour after a health scare and hospitalization earlier this summer.

"She's so happy to be back onstage and is feeling strong. She's working closely with her longtime collaborators, Jamie King and Stuart Price, to put the final touches on the show," said the insider of the "ambitious tour."

Following her London shows, Madonna will be making stops in Copenhagen, Barcelona, Paris and more before wrapping up 2023 with shows in Brooklyn and Washington back in the States.

"I am excited to explore as many songs as possible in hopes to give my fans the show they have been waiting for," she said in a press release when the Celebration Tour was initially announced in January.
