Patsy Kensit, who celebrated her 40th birthday earlier this month, was set to marry in the summer after falling for DJ Jeremy Healy, 46, in August.
The Holby City star confirmed that the relationship had ended.
News of former wildchild Kensit’s plans to marry again surfaced when she was spotted in November with a diamond engagement ring while out shopping in London with Healy.
A spokeswoman said: “We can confirm that they have split and the decision was mutual.”
