Timothée and Kiernan met while working on One & Two together, and became so close they've joked about being siblings (like they were in the film), with Kiernan even suggesting he should change his last name and mentioning that her mom drove him to his last Beautiful Boy audition. Timothée has also talked about how much her family took him in — he lived with Kiernan's family for a bit, and used to chaperone Kiernan on dates.
