Ulvaeus is known for being one quarter of Swedish pop group Abba, who this year celebrated 50 years since their winning performance at the Eurovision Song Contest with their song Waterloo.
The group was comprised of two couples – Ulvaeus and Agnetha Faltskog, and Benny Andersson and Anni-Frid Lyngstad.
The Swedish musician married Abba bandmate Fältskog in 1971. The pair had two children, Linda, 49, and Peter, 44, before divorcing in 1980.
Andersson and Lyngstad also divorced in 1981, a year before the band split.
The quartet did not reform to perform at Eurovision 2024 despite the event being held in Malmo, Sweden.
Ulvaeus was also previously married to Lena Kallersjo, from 1981-2022.
