Klum, 38, filed the petition Friday at the Los Angeles Superior Court. The couple jointly announced earlier this year that they were separating after seven years of marriage. Days later, Seal, 49, said on Piers Morgan Tonight that there was still a chance the couple would get back together.
Klum and Seal began dating in 2003 and got engaged in December 2004. They married in Mexico in May 2005. The pair has three children together: Henry, 6, Johan, 5, and Lou, 2. Seal adopted Klum's 7-year-old daughter Leni from Klum's previous relationship to Flavio Briatore.
