After telling PEOPLEthey were splitting despite “seven very loving, loyal and happy years of marriage,” new details are emerging regarding the split between German supermodel and ‘Project Runway’ host Heidi Klum and hubby Seal.

TMZsays that Seal’s explosive temper is at the heart of the split. Sources close to the couple said that the split was not the result of cheating on either part. It was all related to Seal being unable to control his temper or engage in anger management skills and Klum couldn’t take it anymore. With four young children – they have three biological children together and Seal adopted Klum’s daughter from a prior relationship.

With all that, it seems that Heidi and Seal just couldn't "make it work." The couple have issued a statement where they confirm that they have decided to separate.

 The statement said, We have had the deepest respect for one another throughout our relationship and continue to love each other very much, but we have grown apart. This is an amicable process and protecting the well-being of our children remains our top priority, especially during this time of transition."

Seal will be on the Ellen DeGeneres Show today. According to TMZ, it is unlikely that he will discuss his divorce. Seal was reportedly wearing his wedding ring.

Another source said that this split was in the works for a while, even though the couple looked to have one of those rare, strong and stable celeb marriages. “It was a long time coming,” the source revealed.

Besides Seal’s temper, the fact that Klum’s business career has skyrocketed caused some distance. Seal has a new CD on the way and plans to tour globally, which certainly doesn’t close the gap between them. Currently you hear his remake of "Let's Stay Together" on Lite 98.7.

They remain living under one roof for the time being.
