As Seal opens up about his “split and details about their fight-filled trip to Aspen emerge, friends of the couple reveal that the couple took great pains to hide the cracks in what seemed to be a storybook romance.
“They were just really great at keeping it private and putting on that ‘perfect couple’ front that everyone expected,” says a Klum pal. But “it’s actually been about six months that they’ve been working through some issues.”
“It was a crazy love affair with highs and lows,” says a source close to the couple, known for their over-the-top romantic gestures and lavish anniversary parties. “Most people can’t sustain the highs when they’re that extreme.”
