Jessie also shared a quote from the late Heath Ledger about happiness.
"Everyone you meet always asks if you have a career, are married, or own a house as if life was some kind of grocery list," the quote read. "But no one ever asks you if you are happy."
Earlier this month, ET learned that Jessie and Channing, 39, had broken up after dating since October 2018. At the time, a source told ET that there was nothing dramatic and that the pair remained good friends.
