Is nothing sacred anymore? After seven years of marriage, Heidi Klum and Seal are splitting up, TMZ reports, with inside sources claiming Klum will file divorce papers citing "irreconcilable differences" as early as next week. The couple has three biological (and adorable) children together, and Seal adopted Heidi's eldest daughter from a prior relationship. The once lovey-dovey couple has renewed their vows every year on their anniversary in one lavish ceremony after another. When it comes time to dividing their assets, things could get a little messy. According to Forbes, Klum earned $20 million in the last year alone. It's not clear how much Seal made. While their reps have not confirmed the split, all signs from Seal's twitter feed indicate that their relationship is indeed over.
