According to PEOPLE, Heidi Klum is back on the market because she and Martin Kirstein have split.
The supermodel has split from her bodyguard boyfriend after dating for a year and a half. The 40-year-old began her relationship with Kirstein in 2012, after two months of filing for a divorce from her seven year marriage to British singer Seal.
A friend close to Klum told PEOPLE, “Martin was there for her during a challenging time in her life and it was something she will always be grateful for. 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. They still have a great friendship.”
Klum first announced her new relationship with Kirstein on the Katie Couric’s talk show in November 2012.
Klum told Couric, “he’s been with our family for the last four years. He’s cared for our entire family, mostly for our four children, helped us tremendously. I trust him with my children’s life. He’s a great man…and we just got to know each other from a completely different side.”
Klum shares four children with Seal. Their divorce is not finalized as of this date. At the time of the split, Seal and Klum released a statement which read, “while we have enjoyed seven very loving, loyal and happy years of marriage, after much soul-searching we have decided to separate.”
