The singer and supermodel, who married in Mexico in 2005, announced their "amicable" separation on Sunday.
“In terms of our love and respect for each other, it hasn’t changed at all,” he says in an interview airing Friday on Tavis Smiley on PBS.
On The Ellen DeGeneres Show Wednesday, he said the ring on his finger is “a token of how I feel about this woman.” He also told CNN’s Piers Morgan reconciliation "may happen."
Perhaps she feels the same? Klum’s finger was still adorned with a ring – though it appeared turned upside down – as she left a studio, where she was reportedly at work hosting Germany’s Next Top Model.
