The singer and actress says her “heart is sick” and she’s “praying for her family to be whole again.”

My beloved dogs Koji and Gustav were taken in Hollywood two nights ago. My heart is sick and I am praying my family will be whole again with an act of kindness. I will pay $500,000 for their safe return. Email [email protected] to contact us. Or, if you bought or found them unknowingly, the reward is the same. I continue to love you Ryan Fischer, you risked your life to fight for our family. You’re forever a hero.

I pray Ryan makes a swift recovery and Gaga’s doggies are returned.
