Mastroianni married
Flora Carabella on 12 August 1950. They had one daughter together, Barbara (1951–2018), and informally separated in 1964 because of his affairs with younger women. Mastroianni's first serious relationship after the separation was with
Faye Dunaway, his co-star in
A Place for Lovers (1968). Dunaway wanted to marry and have children, but Mastroianni, a
Catholic, refused to divorce Carabella. In her 1995 autobiography
Looking for Gatsby, Dunaway wrote: "I wish to this day it had worked out." In the 2024 documentary
Faye, she described him as the love of her life. After the break up with Dunaway, Mastroianni began a relationship with French actress
Catherine Deneuve, who was nearly 20 years his junior. They lived together for four years during the 1970s and had a daughter,
Chiara Mastroianni (born 28 May 1972). During their time together the couple made four films:
It Only Happens to Others (1971),
La cagna (1972),
A Slightly Pregnant Man (1973) and ''
Don't Touch the White Woman!'' (1974). After Mastroianni and Deneuve broke up, his estranged wife Carabella reportedly offered to adopt Chiara because her parents' busy careers kept them away from her so often. Deneuve adamantly refused. Mastroianni's other lovers reportedly included actresses
Anouk Aimée,
Carole Mallory,
Claudia Cardinale,
Lauren Hutton and
Ursula Andress. ==Death==
