Heidi Klum and Seal plan to file for divorce in Los Angeles Superior Court this coming week, according to TMZ.
The couple were marred in Mexico in 2005 after having met the previous year.
There has been no comment from their reps. Klum's father, Günther Klum, when reached on his cellphone by the German publication Bunte, sounded surprised by the news and replied, "I don't know anything about it, call me again tomorrow."
The two were reportedly last seen together on Dec. 27, when the supermodel-mom Tweeted a photo of herself and her musician husband in Aspen, reports the Daily Mail.
Project Runway star Klum, 38, was previously married to celebrity hairstylist Ric Pipino and had a daughter – Leni, now 7 – with Italian entrepreneur Flavio Briatore.
She and Seal, 48, also have three children together: Henry Günther, 6, Johan Riley, 5, and Lou, 2.
When she was pregnant with daughter Lou, Klum said of her marriage, "When we're home, we're cooking and doing things with the kids, driving them to school. We do the things that everyone has to do."
