What did Wladimir Klitschko say about Hayden Panettiere’s birthday?

Wladimir Klitschko, Hayden Panettiere's former fiancé, marked what would have been her 37th birthday with an Instagram tribute rather than the celebration he'd planned, since she died on 16 August, days before the milestone [1, 2]. He thanked fans and friends for their support since her death and said he was honouring "her life, her spirit, and the love she brought into the world" [1].
