The 40-year-old model and Martin, 41, split a few weeks ago. The pair started dating a few months after she filed for divorce from her ex-husband Seal.
“Martin was there for her during a challenging time in her life and it was something she will always be grateful for,” a friend of Heidi‘s told People.
“They are no longer working together,” another source said. “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.”
Heidi and Martin were spotted together earlier this month shopping at a local supermarket.
