Heidi Klum is "moving forward" with her divorce from Seal.

The German supermodel - who parted ways from the 'Kiss From A Rose' singer last month after almost seven years of marriage - reportedly thinks it's "best to be away" from her estranged husband as the former couple come to terms with their marital split.

An insider explained: "They have had very little contact and Heidi wants to keep it this way. She feels less stressed out now and feels it's best to be away from Seal, so she doesn't get confused about her feelings.

"She is moving forward with the divorce."

While the couple - who raise four children, Leni, seven, Henry, six, Johan, five, and two-year-old Lou, together - were previously both wearing their wedding rings, it is thought they have given up hope that they might be able to "work it out" and both Seal and Heidi have been spotted without their bands.

The source added to People.com: "They had both been wearing their wedding rings and had mutually thought they might be able to work it out. But it doesn't look like it's going that way."

Following the split, Seal admitted he was keen to continue to wear his wedding ring as a "token" of how he feels about Heidi and he had "no intention" of removing the band anytime soon.

He recently said: "I think it's just pretty much a token of how I feel about this woman. We have eight years. Eight wonderful years together. Just because we have decided to separate doesn't necessarily mean you take off your ring and you're no longer connected to that person.

"Will we wear the ring for the rest of our lives? Who knows? But right now it feels really comfortable on my hand so I have intentions of taking it off anytime soon."
