Born on March 29, 1999, Atiana De La Hoya is the daughter of boxing champ Oscar De La Hoya and Shanna Moakler; she became Barker's stepdaughter when he married Moakler in 2004. Since then, the two have had an undeniably close bond similar to that of her stepsiblings, which she's continued to nurture even after their parents divorced in 2008. You can find the 22-year-old chilling on Instagram as well as showing off her creative talent on her art Instagram page (@artbyatiana), which has made its way onto a custom bag for Machine Gun Kelly.
