Kid Rock made sure the run-up to his 40th birthday on Monday (17Jan11) was one to remember - he performed in front of 45,000 fans in his hometown on Saturday (15Jan11).
The All Summer Long hitmaker organised a concert in his native Detroit, Michigan, with tickets selling out in under 20 minutes.
The star's milestone celebration kicked off in style as he took to the stage to a rendition of Birthday by the Beatles, before fellow musician Uncle Kracker joined him for Good To Be Me.
Kid Rock also received birthday messages from U.S. talk show hosts Conan O'Brien and Jay Leno, who both appeared in taped videos on huge screens at Detroit's Ford Field stadium.
