Heidi Klum and Seal had a seemingly rock solid marriage, but it has been reported that the pair are headed for a divorce.
A source with "direct knowledge" of the situation told TMZ that Klum will file divorce papers in L.A. Superior Court as early as next week and plans to cite "irreconcilable differences."
The cite offered no evidence to substantiate the claim, but mentioned that Klum attended the Golden Globe Awards alone and the last photo she Tweeted with Seal was on December 26, where they appeared happy together.
"It's true and it's a sad end to the fairytale," a source told Access Hollywood on Saturday. "They love each other very much, but they have had a very tense time in the last year."
Klum and Seal's representatives had no immediate comment on the reports and the stars have remained mum on Twitter.
Klum, 38, and Seal, 48, famously renew their wedding vows every year, last year they headed to Palm Beach, Florida and wore costumes and Victorian-style masks.
Klum and Seal officially celebrate their anniversary on May 10. In 2010, Klum told Redbook, "We love to renew our vows. It's our time -- a lovely family time. It's about remembering this moment of love we gave to each other and reinforcing it."
The pair are also known for their lavish annual Halloween party and coordinating costumes (See some of their costumes over the years).
The pair wed on May 10, 2005 and have three children together, Henry Günther, 6, Johan Riley, 5, and Lou, 2. Seal also adopted Klum's 7-year-old daughter Leni, from her previous relationship with Flavio Briatore. Klum was previously married to celebrity hairstylist Ric Pipino.
