Hayden Panettiere‘s ex-boyfriend, Wladimir Klitschko, is paying tribute to the late actress on what would’ve been her 37th birthday. She died Sunday, Aug. 16, just five days prior.

“Today is Hayden’s birthday. Instead of celebrating the way we had planned, today we celebrate her life, her spirit, and the love she brought into this world,” wrote Klitschko. “I want to thank all of Hayden’s fans, friends, and everyone who has reached out for the incredible outpouring of love and support. At a time filled with so much sadness, your kindness has reminded me that there is still so much good in humanity. If you’re reading this, I ask just one thing: even if only for a moment, think about LOVE. Reach out to a friend. Forgive someone. Be kind. Love is a superpower. Use it. Happy Birthday, Hayden. You are loved, you are missed, and you will never be forgotten.”
