Prince Michael, 16, was to have filled in for Paris, 15, on Wetten, dass …? (Wanna Bet?). Paris was originally booked on the program for its summer edition filmed in Mallorca, Spain.
On Thursday, a spokeswoman at German TV station ZDF told PEOPLE that the production team is in contact with Prince Michael’s management, which canceled his trip to Europe.
Said the rep, Silke Blömer, “Under these circumstances, we perfectly understand that Prince Michael prefers to stay close to his family. We wish Paris the strength and the power to recover soon.”
