“I’m missing this one’s birthday party tonight 😢” she captioned a photo from the pair’s Rodarte Spring Summer 2020 Campaign. “I’m so proud of you Kiernan Shipka I feel somewhat responsible for you little one. You have become such a success in life and in this silly world we call work. I couldn’t have asked for a better on-screen daughter/partner in crime. Known you since you were 6! Happy 20th!!! Love Mom 😉.”
