Madonna has crowned MCA one of the best performers and a huge inspiration to her career.
According to TMZ:
"The queen of pop told the AP she felt the Beastie Boys were "integral to the musical revolution that was happening to me at the time." She called his death sad and asked God to bless his family.
The Beastie Boys opened for Madonna during her 1985 Virgin Tour."
The mega star is one of many mourning the loss of the emcee legend who passed away on Friday after a long battle with cancer, just one month after being inducted into the Rock and Roll Hall of Fame.
