Madonna kicked off her Sticky and Sweet tour Saturday night at Cardiff's Millennium Stadium in Wales.

The spectacle was filled with over-the-top costumes, multiple themes, and special video appearances by some of Madonna's famous friends.

Madonna's fans were treated to virtual duets with Justin Timberlake, Kanye West, and, yes, Britney Spears.

 

During the the two-hour bonanza, M teased the audience, telling them, "This is the bit where I take request." she started to sing "Express Yourself", then stopped, and said, "F*ck that sh*t. I choose the songs."
