Heidi Klum has filed for divorce from Seal.

The 38-year-old supermodel - who split with the singer in January after almost seven-years of marriage - has cited "irreconcilable differences" in her divorce petition which was filed at the Los Angeles Superior Court, TMZ.com reports.

According to documents filed by Heidi'slawyer, Laura Wasser, and obtained by the website, the couple signed a pre-nuptial agreement when they tied the knot in 2005 detailing how they would split their assets.

The couple have four children - Leni, seven, Henry, six, Johan, five, and two-year-old Lou - and Heidi is seeking sole physical custody of their kids with Seal getting visitation and joint legal custody.

The blonde beauty also wants the judge to restore her maiden name, Klum, which she uses professionally.

Following the announcement of the couple's separation, the "Kiss From A Rose" hitmaker revealed the pair had "grown apart" and he insisted he still "very much loved" the 'Project Runway' star.

The 49-year-old star explained: "You just grow apart after a while. She still, in my opinion, the most wonderful woman in the world. I think our priority was to remain civil and do this thing with dignity. We still very much love each other.

"To say that neither of us were grieving would be an out and out lie, and I don't mind telling you that. I think the operative here is that we are civil to each other and we both have a tremendous amount of respect and love and we try and do this with as much dignity as we possibly can."
