Matthew Mellon, the billionaire banking heir, died suddenly at a rehab facility in Cancun, Mexico. He was 53.
Mellon was the ex-husband of Jimmy Choo co-founder Tamara Mellon, with whom he shares one child, daughter Araminta. He was previously married to designer Nicole Hanley, who he shared two children with, Force and Olympia.
A rep for Tamara did not immediately respond to PEOPLE’s request for comment.
In a statement by a family rep obtained by Page Six, Mellon “died suddenly in Cancun, Mexico, where he was attending a drug rehabilitation facility.”
