Jaycee Chan released his first Mandarin CD album in Hong Kong and later went to Taiwan to continue his music career.
Much like his dad, Jackie Chan, Jaycee established himself in Asia and became a flourishing musician before he broke into the Western industry.
John Ritter (29) & Jason Ritter (29)
This million-watt smile isn't the only thing John Ritter passed on to his son, Jason. Papa Ritter is most known for his role in the '70s sitcom "Three's Company," which he started acting in when he was only 28.
His son, Jason, turned to acting just like his father and has been in several television shows and movies by his late 20s. Losing John was hard for fans everywhere, but lucky for us, whenever we miss the late actor, we look at Jason!
Robert Downey Jr. (26) & Indio Falconer Downey (26)
Robert Downey Jr.'s oldest son almost looks like he could be his dad's brother—you know, minus the beard and long hair.
Like his dad, Indio also decided to go into the entertainment business. In 2005, Indio appeared in his father's film "Kiss Kiss Bang Bang," and he's also dabbled in the music industry as a performer in several bands.
Gary Busey (47) & Jake Busey (47)
Gary Busey had an incredible career back in the 70s and 80s, especially when he garnered acclaim for his role in "The Buddy Holly Story."
His son, Jake Busey, has carried on in the same style; he starred in films like "Starship Troopers," "Identity," and, most recently, the popular Netflix series "Stranger Things."
Will Smith (23) & Trey Smith (23)
Many will know Trey as Will Smith's more discreet son, but he's also Will's oldest son. Trey also has his dad's ridiculous good looks and incredible smile.
We haven't seen much of Trey yet, he's only appeared in a few small roles here and there, but we can't help but wonder if he'll have the same relentless energy as his father.
