After a number of show cancellations because of a serious health scare, Madonna’s long-awaited Celebration Tour finally began on Saturday night.

At age 65, the legendary “Queen of Pop” took the stage at London’s O2 Arena in Greenwich with a huge 45-song set list that showed off her amazing 40-year career.

Even though the show was supposed to start at 8:30pm, it started about 20 minutes late. In the meantime, a drag queen act kept the audience entertained.

Madonna, who is known for performances that push the limits, did not fail with one of her most sexy concerts to date.

The star looked her usual bold self while wearing a sexy red corset and being surrounded by dancers without tops.

But there was a short break in the show because of technical issues right after it started, which made the evening a little less predictable.

“This is exactly what you don’t want to happen on your opening night!” Madonna told her fans during the exciting performance of her Celebration Tour, making fun of the first technical problem.

The Queen of Pop also talked about how strong she was, saying that her long career was due to both her fans’ loyalty and her own drive.

The show had captivating performances of her most famous songs, such as “Like A Prayer,” “Live To Tell,” “Holiday,” and “Nothing Really Matters.”
