Seal has hinted he may be able to work things out with estranged-wife Heidi Klum.

The couple announced their separation after almost seven-years of marriage earlier this week.

The British singer has continued with promotional duties for his new album Soul 2, including sitting down for an interview with Piers Morgan which will air later this week.

Asked if there is any chance he might reconcile with the German supermodel, Seal replied: "You can never say never.

"I don't know at this point if I would like to get back together. If it were that easy, we would still be together, that is the reality

"Whether we get back together or not, it may happen, I can't speak for her."

The 48-year-old spoke about the issues he and Heidi have faced. They have claimed their split is amicable, but he explained they have had arguments.

"I can't speak for my wife and I'm not going to sit here and BS you and say we haven't had problems. Of course we have had problems, otherwise why have we split up?" he said.

"This is not a charade. We have problems, we have issues, but to our credit we have always been able to talk about them, to confront them. To assume that any couple goes without arguing is just nonsense."

Seal is still wearing his wedding ring. He discussed why while on the Elle DeGeneres show this week, saying it's a symbol of all he had with Heidi.

The star is dismayed that some people have questioned whether that is the truth.

"There was some malicious thing about me still wearing my wedding ring for show but I'm still wearing my wedding ring because I am still married to this incredible woman and you don't all of a sudden from one day to the next, unless you are those type of people, say I hate you and take off your wedding ring," he fumed.

He added one of the best things about his marriage was he and Heidi always managed to work on their issues. They argued, but always cleared things up and never let "outside influences" affect them.

"I always used to say to my wife, the thing that I loved most about us is that we are a team, we are impenetrable in that respect," he recalled.

Meanwhile, People magazine has alleged Seal and Heidi have been working on issues for some time.

"They were just really great at keeping it private and putting on that 'perfect couple' front that everyone expected," a source told the publication.

"It's actually been about six months that they've been working through some issues."
