Personal life
Andress has stated that she lost her virginity to married actor Daniel Gélin in 1953, when she was 17 and he was 32. She dated Dennis Hopper and James Dean after moving to the US in 1955, and that same year began an affair with actor/director John Derek, a married father of two who left his wife, Pati Behrs, and their family to be with 19-year-old Andress. Derek and Andress wed on 2 February 1957, in Las Vegas, but separated in 1964 over her affair with Once Before I Die co-star Ron Ely, officially divorcing in 1966. Prior to the finalization of her divorce, Andress publicly dated John Richardson, her co-star from She, and Marcello Mastroianni, her co-star from The 10th Victim.
From 1965 to 1972, Andress lived with her Up to His Ears co-star Jean-Paul Belmondo. She has stated that Belmondo was the love of her life. Her next live-in relationship was with another co-star, Stateline Motel's Fabio Testi, from 1973 to 1977 (except for one year when they broke up). She also dated Ryan O'Neal, John Delorean, Helmut Berger, Paolo Pazzaglia, Johnny Dorelli, Franco Nero, with whom she later starred in Red Bells, Carlos Monzón, Nels Van Patten, and Ricci Martin.
When Andress broke her arm in 1978, the official story was that she had been struck by Hurricane Norman while bodysurfing in Malibu, but it was rumored that she actually suffered the injury during a fight with her on-again/off-again boyfriend O'Neal. O'Neal and Andress were in a relationship twice, first from 1972 to 1973, then again from 1977 to 1978.
Andress lived with actor Harry Hamlin after meeting on the set of Clash of the Titans in 1979. She gave birth to their son, Dimitri Alexander Hamlin, on 19 May 1980. The night of her delivery, Linda Evans drove Andress to the hospital while Evans's assistant Bunky Young retrieved Hamlin from the set of King of the Mountain. Although she was engaged to Hamlin, the couple never married. Hamlin ended their relationship in 1983.
In the mid-1980s, Andress was romantically involved with soccer player Paulo Roberto Falcão, actor Gerardo Amato, singer Julio Iglesias, real estate developer Stan Herman, and bodybuilder Mario Natokis. In 1986, she began dating Fausto Fagone, a future Sicilian Regional Assembly member. He was 20 and she was 50. The relationship, which infuriated Fagone's parents, lasted until 1991. Later that year, Andress briefly dated martial arts expert Jeff Speakman, but has not been publicly linked with anyone since.
In 2017, Andress sold her home in Beverly Hills at a considerable profit. She also has resided in Florida, Virginia, and Spain. As of 2022, Andress splits her time between a home outside Rome and a house in Gstaad, near her siblings. Her preferred language is Italian.
Andress's business manager, Eric Freymond, committed suicide in July 2025, after which it was discovered he had embezzled $23 million from the actress. In 2026, she successfully sued Freymond's estate to recover her stolen fortune.
