If you watch the video, Elton makes his remark in a very kind and joking way.. no harm intended
So does Madonna,,, referring to an old joke.. presented in fun and kind manner..
I may have the answer for David's Furnish outburst. In september of 2008 when the Sticky and sweet tour hit Nice in France, he threw a party in her honour she did not attend. He had evrything planned, the (****ing asshole) mayor of the city was there, Bono too and the press had been invited to cover the event. Madona was on the second night only of her world tour and declined the invitation. Then there is the ongoing feud between her and Elton John since Madonna and Demi decided to throw their own post-oscars party at Guy Oseary's house that same year. Since 2008 the Madonna and Demi post oscars party with a no press allowed policy and a strict invites only entry became the most sought after party by celebrities leaving Elton John's bash to reality tv stars and D list celebrities, to sum it up > his crowd
