His last name tells it all, John is indeed a legend. He does it all, from singing and writing to producing and acting. He shared a throwback image of himself as a young kid, and if you look at pictures of his son, Miles, from the same age, the resemblance is uncanny.
John has admitted to being truly jealous of his son Miles, who, even at such a young age has an amazing fashion sense.
Guy Ritchie (20s) & Rocco Ritchie (20s)
Being the son of famous director Guy Ritchie and global icon Madonna sounds like a lot of pressure. Guy's first film came out in 1995 when he was in his late 20s, while Madonna had her first-ever hit at the tender age of 24.
No matter what you do, you will always find yourself compared to your successful parents. Rocco took a different path and has made a name for himself as a painter and has even presented at the Tanya Baxter Contemporary Gallery in London.
Harry Hamlin (30s) & Dimitri Alexander Hamlin (30s)
Dimitri Alexander Hamlin, son of Harry Hamlin and Ursula Andress, is a star in his own right. While Ursula is a Swedish actress and model, Harry is known for his roles in classics like "Clash of the Titans" and "L.A. Law."
Born in 1980, Dimtri found himself following his father's footsteps, taking part in several acting projects, as well as gaining a social media presence.
Orlando Bloom (6) & Flynn Bloom (6)
We don't know a lot of girls who didn't swoon over Orlando Bloom when they were teenagers, or even now. Flynn Bloom, the son of Orlando Bloom and of model and businesswoman Miranda Kerr, is likely to follow in his father's footsteps.
At such a young age, it is still unknown which route Flynn will take in his life, but no matter what he chooses, with such a father, the sky is the limit.
George Harrison (20s) & Dhani Harrison (20s)
The only child of George Harrison, Dhani Harrison, worked on his father's musical legacy before becoming a musician in his own right.
Dhani's own band, thenewno2, was originally a collaboration between Harrison and drummer Oliver Hecks; their sound combines Beatlesque vocals with modern loops. Dhani's solo debut, In/Parallel, presented Dhani's vision of psychedelia, combining trance-hop elements with obvious Beatles roots.
