Björn Ulvaeus Explains Love Beyond Age Differences in New Interview

COPENHAGEN, Denmark — Björn Ulvaeus, one of the iconic voices behind ABBA, spoke candidly about his relationship with his wife, Christina Sas, and the 28-year age gap they navigate. In an interview published Thursday, the Swedish musician, set to turn 80 this month, shared how meeting Sas, who is 52, felt like ‘love at first sight.’

Despite the immediate attraction, Ulvaeus admitted to grappling with his insecurities regarding their age difference. ‘Immediately I had severe problems with myself and the age difference. When a man or a woman meets someone much younger and falls in love they think, ‘Am I doing the right thing?’’ he recalled.

Ultimately, the ABBA star chose to embrace his feelings. ‘In the end, I just gave up. I decided, “It’s up to her — if she wants to live with someone older and we love each other…”’ he explained, emphasizing that their age gap rarely comes up in conversation now.

Ulvaeus characterized what ‘love at first sight’ means to him as ‘spectacular’ and ‘fantastic.’ He stressed the significance of being emotionally open in relationships. ‘You have to be very open, with your antennas out. You have to be adventurous and ready to take a chance,’ he said.

The couple, who began dating in spring 2022 shortly after Ulvaeus’s divorce from his second wife, music journalist Lena Källersjö, married in September 2023. This is Ulvaeus’s third marriage; he was previously wed to fellow ABBA member Agnetha Fältskog from 1971 to 1980, and they share two children, Linda and Peter.

In addition to discussing his personal life, Ulvaeus addressed the success of ABBA’s ongoing concert series, ABBA Voyage, which features digital avatars performing the band’s greatest hits. Currently running in London, the show is scheduled to continue until January 2026 thanks to high demand.

Looking ahead, Ulvaeus acknowledged uncertainties surrounding the future of the concert series, particularly concerning how long it should continue. ‘We are allowed to stay in our current venue until 2029, but ticket sales might drop, you never know. Is it right to continue when someone is dead? That’s a big ethical question,’ he said.

He likened its longevity to that of Agatha Christie’s play ‘The Mousetrap,’ which has been performed in London since 1952, wondering, ‘Did Agatha Christie have a problem with ‘The Mousetrap’? When you’re gone, you’re gone, but… my kids might appreciate it,’ he added.
