The actress, 24, took to Instagram on Monday to thank fans for their support, writing that their prayers have given her strength.
“Receiving all of your prayers and kind words over the past week has given me strength during a time I thought strength could not exist,” she wrote. “There are no words to express how much I will miss my Abadaba and my one and only Momby. Your love and support means the world to me.”
Along with the heartfelt message, Lourd posted a vintage photo of herself making a silly face as her mother and grandmother smiled for the camera.
