Isabella Justice Hartley
Justin's only child, Isabella, was born July 3, 2004. Isabella and Justin are very close — they go to events and spend plenty of quality time together while Justin's not working. Justin's fans have watched Isabella grow up on his Instagram, and now that she's a teenager, she's starting to date — something Justin's decidedly not excited about. He told Jimmy Fallon in 2019, "I know [dating is] a natural thing; it's a healthy thing. She's wonderful. She's sweet. She's responsible. She's great. She's earned the trust. But I hate it — I hate all of it."
Justin and Lindsay had an amicable divorce in 2012 and have been successfully coparenting Isabella ever since. Justin told Us Weekly in 2019 that it's all about communication. "Communication and an understanding of where everyone's coming from and realizing that it's hard. As much as you try to put yourself in other people's shoes, you're never fully going to be able to do it, but you should just make the effort." He also said Isabella is very smart and self-sufficient — something any parent would love!
