According to the Inside Out actor, he keeps a tight lip about his relationships in order to better preserve his children's privacy. Bill has three daughters—Hannah, 12, Harper, 9, and Hayley, 7—with his ex-wife Maggie Carey, whom he divorced in 2018 after 11 years together.
Instead, Bill, who will star in the upcoming third season of the HBO series Barry starting April 24, gave insight into his relationship with his kids.
"They just want me to be their dad," he told the outlet. "They just want me to sit and watch Encanto over and over and over again. So that's what I do."
Back in January, news broke that Bill and Anna had been secretly dating for more than a year.
The pair, who first met years prior, saw sparks fly after they starred opposite each other in the 2019 Disney+ holiday film Noelle.
"It's been going on for quite a while," a source told E! News at the time. "Anna's kept it really on the DL."
