Madonna has written a song for ex-husband Guy Ritchie, triggering speculation that the couple may back together.

The pop diva, who divorced the British film director earlier this year after almost eight years of marriage, recently penned a song about a former couple who reunited, raising speculation that they are set to reconcile, The Sun claims.

“Madonna has met few people in her life she truly respects and one of them is Guy. Forgetting everything else, she admires his intellect and cares about what he thinks. No one ever expected they could go from lovers to enemies and then back to incredibly close friends,” says a source
