Jonna Lundell co-runs the YouTube channel "Familjen Lundell" with her husband Joakim Lundell.
Together with comedian and "Best in Test" winner Torbjörn Averås Skorup, she is one of two new participants revealed for "The Traitors".
The new season premieres on TV4 on April 16.
It was already known that former Social Democratic Party leader Mona Sahlin, singer Miriam Bryant and Anna Anka will also be included in this spring's edition.
"The Traitors" is filmed at Häringe Castle outside Stockholm. The show is based on a Dutch format and involves more or less famous people being locked up in a castle, where some of them are designated "traitors" while the rest are "loyal".
