On April 17 2008, Madonna posted a message for her fans on YouTube from the set of the Give It 2 Me music video in London. In the message, Madonna thanked her fans for making videos for 4 Minutes, and reminds them to clean up after themselves.
Watch the message:
Today In Madonna History 
Even as she reached her half-century mark, Madonna was not slowing down-Hard Candy actually has some good songs on it namely Four Minutes and Give It to Me.
The whole CD rocks actually.
