Supermodel Heidi Klum reportedly broke up with her bodyguard boyfriend Martin Kirsten a few weeks back.

The 40-year-old, who started dating Kirsten after ending a marriage of several years, is said to be grateful for the support he gave her.

“Martin was there for her during a challenging time in her life and it was something she will always be grateful for,” people.com quoted a friend, close to Klum, as saying.

Not only have the two split up, but have stopped working together as well.

“They are no longer working together…life is about timing. He was incredibly supportive and they were there for each other, but they’re moving on now,” another source said.
