Heidi Klum and Seal have officially broken our hearts. On Sunday night, the couple confirmed that they are indeed calling it quits after nearly seven years of affection-filled marriage.

"While we have enjoyed seven very loving, loyal and happy years of marriage, after much soul-searching, we have decided to separate," they said in a joint statement. "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."

Insiders say the supermodel-turned-"Project Runway" mogul, 38, and the British crooner, 48, had recently hit a rough patch.

"They're either madly in love or having crazy fights," a spy tattled to Us Weekly.

Those supposed squabbles marred their holiday trip to Aspen, during which Heidi tweeted the lovey-dovey photo at left.

"They fought a lot," sighs the snitch. "It was a very hard trip."

Two days ago, Seal tweeted a cryptic photo with the message, "The End."

In their announcement, Klum and Seal called the breakup "amicable."

"Protecting the well-being of our children remains our top priority, especially during this time of transition," they added. "We thank our family, friends, and fans for their kind words of support. And for our children's sake, we appreciate you respecting our privacy."

The pair, who tied the knot on a Mexican beach in May 2005, are parents to Leni, 7, Henry, 6, Johan, 5, and Lou, 2.

During the course of their romance, they seemed like a perfect match, from their mutual glee over Halloween to their annual vow renewal.

And before we kick ourselves for believing in true celebrity love, let's remember Heidi and Seal in happier, more PDA-packed times.

Wow, this was so shocking to hear this morning! They were such a great couple, but the rumor report I heard stated that Seal had a very bad temper and Heidi didn't want him to possibly harm the children because of it. Wow. I am glad to read that their separation was amicable, so this is a good sign of peaceful divorce proceedings.

Good luck to them all.
