Elton John's claws are out when it comes to Madonna. He has firmly sided with Lady Gaga in the feud between the two pop divas. Duh.
Gaga is godmother to the Rocket Man's son Zachary, so of course he's got her back and is Team Gaga, as opposed to Team Madge. In the process of defending his son's godmother, of whose praises he sings, he takes a big ol' slap at Madge. Elton was, in fact, brutal and downright nasty with his diss of Madge.
