Kerry Katona's 19-year-old daughter, Heidi, has made a public comment on TikTok about her father, Mark Croft, questioning his suitability to offer relationship advice. The remark comes 16 years after Katona and Croft's separation.

Heidi stated in a TikTok post that one should not seek relationship advice from her mother, Kerry Katona, because she married Mark Croft. Katona and Croft had a tumultuous relationship, which ended in 2011 after marrying in 2007. They share two children, Heidi and her brother Maxwell, 18. Neither Heidi nor Maxwell maintain a relationship with their father.

Katona has previously spoken about her difficult relationship with Croft, a former taxi driver, whom she accused of contributing to her past struggles with drug use, an allegation Croft has denied. Their highly public breakup was marked by accusations of infidelity on both sides. Katona later admitted to having an affair with Kevin Green during their marriage, calling it the "best thing that I ever did."

Following their split, Mark Croft has largely withdrawn from public life. He has since remarried and lives in Bolton with his second wife, Kelly Croft, 38, whom he married in 2016. The couple has one child together, and Mark also has a daughter from a previous relationship. Little public information is available about Croft's life since his separation from Katona.

Katona, who has been married three times previously, is currently in a relationship with Paolo Margaglione. Her previous marriages include a union with singer Brian McFadden, with whom she has two daughters, Molly and Lilly Sue, and a marriage to the late George Kay, with whom she had a son, DJ. In 2023, Katona mentioned that she and her children had no contact with Mark Croft, but she had informed Heidi that she could facilitate contact if she wished.
