No one can replace Seal. So Martin Kristen and Heidi Klum broke up and he's got to find a real job again now. From People:
It was fun while it lasted, but it looks like Martin Kristen has to get a real job again. Heidi Klum just dumped his ass. From People:
After dating for a year and a half, the supermodel and her bodyguard boyfriend Martin Kirsten separated a few weeks ago, People confirms exclusively.

"Martin was there for her during a challenging time in her life and it was something she will always be grateful for," says a friend close to Klum. "Life is about timing. He was incredibly supportive and they were there for each other, but they're moving on now. They still have a great friendship."
"Great friendship is code for no more contact with one another".
