Furnish caused controversy earlier this year when Madonna beat his husband Elton John to a Golden Globe for 'Best Original Song', as he later described her as "desperate" and also claimed that she cannot make good movies.

John has also publicly slammed Madonna, claiming in August that her career was over and that her tour had been a "disaster".
However, Furnish - who previously claimed that his Golden Globe comments were blown out of proportion - has now attempted to move on from the feud.
Asked by TMZ about whether Madonna is past her prime, he said: "No, not at all. I think she's a great artist and I wish her all the best.
"I think she is a great artist and I think she works very, very hard. She is an inspiration to all of us and I wish her all the best."
Furnish added: "Seriously, I love her. I wish her all the best."
Madonna has previously forgiven John for his comments about her, explaining that he is a "big fan".
