Before Jeremy Allen White and estranged wife Addison Timlin separated after nearly four years of marriage, they frequently doted over their two daughters. “From the moment you were born you found all the places that needed more love and you poured it in,” Timlin gushed via Instagram in October 2022 of her eldest daughter, Ezer, […]
Years prior to their split, Dermot discussed why he was not pressuring his kids to follow in his Hollywood footsteps.
“I try to keep arts in front of them, whether it’s music or even just museum trips. I don’t expect anything of them — it’s hard enough for everyone just to get their homework done at night,” he told Hollywood News in January 2016. “Let’s just get them through grade school, and then see. We’ve all certainly seen that being a child actor is unhealthy so, I wouldn’t do that.”
When asked what his kids thought about his acting career, he said, “I think there’s mainly indifference. It’s just the comings and goings; whether I’m home or not.”
