The model has reportedly decided to call time on her relationship with bodyguard, Martin Kirsten, a few weeks ago, after a year and a half of dating

The couple had initially got together shortly after Heidi, 40, had split form her husband Seal in January 2012 after seven years of marriage. Unsurprisingly, Seal wasn't entirely OK with that. Strange because usually he's such a laid back guy...

A source told People.com: "Martin was there for her during a challenging time in her life and it was something she will always be grateful for. Life is about timing. He was incredibly supportive and they were there for each other, but they're moving on now."

Heidi - who has Lou, four, Henry, eight and Johan, seven from her marriage to Seal and Leni, nine, from her relationship with Flavio Briatore - has also cut professional ties with Martin, 41. So, in short, he's lost his (famous) girlfriend and his job.

When the couple initially got together, Heidi said of Martin: "He's been helping me for four years now, and he takes wonderful care of the kids. He plays with them, he protects them. I trust him." He was also on hand when to help saved Henry and two nannies from a riptide in Hawaii which could have drowned them in early 2013.

Ah well, least he has the memories.
