Madonna, the iconic Queen of Pop, is back in action and ready to reclaim her throne on the global stage. After a harrowing health scare in June, which saw her hospitalized and intubated due to a severe bacterial infection, the superstar is now gearing up for what insiders describe as her "most ambitious tour" to date.

The 65-year-old singer's health ordeal was a shock to fans worldwide. Reports indicated that the severity of her condition required doctors to revive her with Narcan. However, Madonna's indomitable spirit shone through as she embarked on a rigorous recovery process post-discharge. Her dedication to her craft and her fans became evident as she began preparations for her previously postponed tour.

According to an exclusive source who spoke to People, Madonna officially resumed her rehearsals on Monday. The insider shared, "She's so happy to be back onstage and is feeling strong." The source further revealed that Madonna has been collaborating with her longtime associates, Jamie King and Stuart Price, to add the finishing touches to the upcoming show.

The Celebration Tour, as it's aptly named, is not just another concert series for Madonna. It marks the 40th anniversary of her illustrious career and serves as a tribute to her "Celebration" album. The tour promises to be a grand spectacle, with the singer set to kick things off with four sold-out shows at London's O2 Arena. Following her UK stint, Madonna will head to North America, beginning with three back-to-back performances at Brooklyn's Barclays Center.

Madonna's recent birthday celebration in Lisbon was a testament to her resilience and gratitude. The "Back That Up To The Beat" hitmaker expressed her profound appreciation for life, especially after her recent health challenges. While she cherished the moments with her family, her focus has now shifted entirely to her upcoming tour.

In addition to her tour preparations, Madonna has made waves on the music charts. Her song, "Popular," secured the No. 40 position on Billboard's Radio Songs chart. This achievement marks her return to the top 40 after over a decade, adding yet another feather to her cap.

Madonna's journey, from her health scare to her imminent tour, is a testament to her enduring spirit and commitment to her art. As fans eagerly await her return to the stage, one thing is clear: The Queen of Pop is back, and she's ready to dazzle the world once more.
