Isabella Justice Hartley was born July 3, 2004. She is Justin Hartley's only child. Isabella and Justin are very close, going to events together and spending 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 last year, "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 successfully been coparenting Isabella ever since. Justin told Us Weekly last year that it's all about communication. "Communication and an understanding of where everyone's coming from and realising 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!
