The Dutch entrant was disqualified from the Eurovision Song Contest just before the grand final due to a backstage incident involving a female crew member.
Klein's song "Friesenjung" was a number one hit in Germany, Switzerland, and Austria in 2023, earning him a Best Song award in Germany.
His Eurovision entry, "Europapa," is described as a '90s era song and a 'love letter' to his late father, breaking records for the most streamed song in a single day on Spotify in the Netherlands.
Klein was scheduled to perform at the Malmo Arena in Sweden, but he was a no-show, leading to his performance being skipped without explanation.
Speculation arose regarding Klein's absence potentially relating to his clash with Israeli journalists and allegations of a rift between him and Israeli performer Eden Golan, sparking controversy surrounding this year's competition.
The disqualification added to the existing controversy over Israel's participation in the contest, which has sparked protests from Palestinians and their supporters.
Reports suggest Klein is being investigated after an incident involving a television production worker, resulting in his disqualification from the live final.
The European Broadcasting Union (EBU) confirmed the disqualification of Joost Klein and stated that the incident did not involve any other performer or delegation member.
The EBU stated that it would not be appropriate for Klein to continue in the competition while the legal process was ongoing, citing a breach of contest rules due to his behavior towards a team member.
Klein's disqualification was confirmed by the EBU, emphasizing their zero-tolerance policy towards inappropriate behavior and their commitment to providing a safe working environment for all staff at the Contest.
The incident adds a layer of controversy to the Eurovision Song Contest, impacting both Klein's career and the Netherlands' representation in the competition.
In light of recent events, Klein and the Netherlands were immediately disqualified from the Eurovision Song Contest, with Klein last seen briefly at rehearsals before missing his performance.
