In 2003, Madonna broke the internet with her iconic performance at the VMA's.

The Queen of Pop took the stage with a joint performance with Britney Spears.

The "Holiday" singer took things to the next level by kissing Spears on stage.

Madonna confessed that the kiss was one of her most memorable moments.

Aside from sharing a kiss, the pop stars were longtime friends.

Madonna was part of the people who fought for the end of Spears conservatorship.

The 63-year-old was hellbent on avenging the cruelty her friend endured.

After 13 years, Britney finally gained freedom from her father, Jamie Spears.

Madonna showed off her fun side with a unique workout routine on Instagram.
