Access Hollywood's sources have confirmed reports that the supermodel/"Project Runway" host is set to file for divorce from the "Kiss From A Rose" crooner.
"It's true and it's a sad end to the fairytale," sources told Access on Saturday.
Adding, "They love each other very much, but they have had a very tense time in the last year."
Heidi, 38, and Seal, 48, tied the knot in May 2005 and are known for renewing their vows in extravagant ceremonies each year.
The couple have three biological children together - Henry, 6, Johan, 5 and 2-year-old Lou.
Heidi has a 7-year-old daughter, Leni, from a previous relationship, whom Seal adopted.
Reps for the couple were not immediately available for comment on the reported split when contacted by Access on Saturday.
