According to showbizzwatcher Jelle Brans in Het Laatste Nieuws, the pop trio K3 faces a new management puzzle at Studio 100 as member Marthe De Pillecyn returns from maternity leave while groupmate Hanne Verbruggen prepares to step away for her own pregnancy.
The End of Klaasje Meijer’s Temporary Return
Marthe De Pillecyn’s recent maternity leave brought former member Klaasje Meijer back to the stage alongside Hanne Verbruggen and Julia Boschman. Meijer departed the group in 2021, but stepped in to cover the temporary absence during the summer months. According to Brans, that temporary replacement window officially closes on October 1, when De Pillecyn resumes her duties with the group.
Studio 100 Evaluates a K4 Joker Pool Concept
Management at Studio 100 must quickly address a secondary staffing gap because Hanne Verbruggen will reach roughly the midpoint of her pregnancy by October 1. Industry reporting from Het Laatste Nieuws indicates that studio executives discussed establishing a flexible “K4 pool” concept behind the scenes. Under this proposal, Meijer would not rejoin the permanent lineup as a full-time member, but would instead serve as an on-call utility performer whenever a current singer takes temporary leave.

Why a Permanent Comeback Appears Unlikely
Despite receiving positive reception for her summer appearances—with Brans noting that Gert Verhulst was very content with what he termed the “Klaasje-effect”—a long-term return remains improbable. Sources cited by Het Laatste Nieuws reveal that Meijer harbors serious doubts about putting her established life and ongoing professional projects in the Netherlands on hold for another extended period. Consequently, Studio 100 will likely need to pursue alternative replacement strategies to ensure uninterrupted touring and performance schedules.
