In July of this year, Collins wrote him a romantic love note to celebrate his birthday.
"You’re a true gift of a human @charliemcdowell. An incredible boyfriend and the best dog dad to @redforddog," she wrote. "You’ve opened my eyes and deepened my heart. You constantly inspire me to dream big and go outside of my comfort zone."
"Every day is an adventure with you and I can’t wait to explore more of the world together (when we can). I love you so much…" she concluded.
