She was born Catherine Spaak in Boulogne-Billancourt, a western suburb of Paris, on 3 April 1945. Her father was the Belgian screenwriter Charles Spaak and her uncle, Paul-Henri Spaak, was a Belgian prime minister. She
got her big break into acting in 1959
with a bit part in the film Le trou. When she moved to Italy later that year, her father introduced her to film director Alberto Lattuada, who cast her in his film I dolce inganni, which was released in cinemas in 1960.

Further film roles followed, including Le puits aux trois vérités (Il pozzo delle tre verità), La voglia matta, Diciottenni al sole and, in her first lead part, L’amore difficile. She played a variety of adolescent, Lolita-type roles and became hugely popular.Her screen success, combined with her love of singing and playing the guitar, led, almost inevitably, to an offer of a recording contract. She signed with the Ricordi label in 1962.
Given her star status, she was teamed with the label’s top talent. Perdono – written by Gino Paoli (who had worked with stars such as Mina) and arranged by Ennio Morricone – was issued as her debut single and swiftly made the Italian top 20. Vocally, Catherine drew comparisons with France’s newest star, Françoise Hardy, so Ricordi opted to have their young signing record a couple of Hardy songs for the Italian market.

Her acting career had continued unabated during this period, and she even appeared alongside Jane Fonda in Roger Vadim’s La ronde. The very Hardy-esque Questi vent’anni miei, taken from the soundtrack of the film I malamondo, became her first single of 1964. Non è niente, from the film La calda vita, was issued as the follow up, but despite the success of the film, the single could only scrape into the top 30. No matter. An appearance at the Festivalbar song contest with L’esercito del surf – penned by top songwriters Mogol and Vito Pallavicini – soon saw Catherine return to the charts. The song remains one of her best known hits.
Among her most notable film titles of the 1960’s are Circle of Love (1964, directed by Roger Vadim), The Man, the Woman and the Money (1965, starring Marcello Mastroianni), The Incredible Army of Brancaleone (1966, written by Age & Scarpelli), Adultery Italian Style (1966), Hotel (1967), the sex comedy The Libertine (1969), Diary of a Telephone Operator (1969, with Claudia Cardinale),

After appearing opposite Rod Taylor in the US film Hotel in 1967, Catherine cut her first record in over a year – the lounge-tastic La notte è fatta per rubare, from the soundtrack of a film of the same name. From this point on, she went into the recording studio only sporadically.
Seeking a new direction, she joined fellow singer Johnny Dorelli in the operetta La vendova allegra in 1968. The pair went onto enjoy a lasting relationship, both personally and professionally. She also switched record labels, joining Det for the release of Igor e Natacha (another Mogol composition). After a couple more solo singles, Oh! and I regali del passato, Catherine joined up with Dorelli to enjoy success as a duo with songs such as Song sung blue in 1972 and Una serata insieme a te in 1973.

More recently she competed in reality TV show "L'isola dei famosi" (Italian version of "Survivor") briefly in 2015 but dropped out citing safety concerns and said she would not risk her life for a game show. She is still continuing her acting, principally in the theatre.
