Ruby Park, born in May 2012, is the first and, so far, only child of Randall and Jae Suh Park. At an early age, Ruby got to "act" alongside her parents: she starred as a crime-fighting baby superhero in Baby Mentalist, a comedy webseries that her father created back in 2013.
In a 2014 interview with LA Weekly, Ruby apparently showed off her big personality, even though she wasn't even two years old yet! "She quietly leads [her parents] from the family room (where she flips through her picture books), to her playroom (where she rocks the keyboard while using her drum as a stool), and finally to the master bedroom, where, snuggled in between two pillows twice the size of her body, she entertains herself by clicking through YouTube videos on Jae's tablet. ("She once flagged a kid's video for adult content," Jae says)," writer Ada Tseng noted.
As Ruby has grown up, her parents have kept her pretty much away from the public gaze. Randall Park doesn't have an Instagram, but his wife Jae Suh does, and she's shared a couple of cute pictures of dad and daughter over the years.
