When actor Macaulay Culkin joked on "The Joe Rogan Experience" in 2018 that his children with girlfriend Brenda Song would be like "a bunch of Sean Lennons running around," one thing at least became evident: The son of Yoko Ono and John Lennon had become something of a pop-culture phenomenon himself. With those parents and Sir Elton John as his godfather (via Smooth Radio), this probably isn't too surprising.

After Sean's birth in 1975, John strayed from music to focus on fatherhood, a fact resented by his older son with ex-wife Cynthia, Julian, according to The Telegraph. Despite this, Sean and Julian have always appeared close in the public eye. The younger half-brother once reportedly divulged that "Julian is the reason I started playing music"(via the U.K.'s Express).

As a musician, Sean knows the double-edged sword of living under a famous father's shadow within the same industry. "Honestly, I don't play music in terms of trying to compete with my dad, because I don't think I could play if I did that," Sean shared with "The Talk" in 2020 (via The Ville). With his John-esque round, wire-framed spectacles and Ono-esque heart-shaped face, Sean, however, welcomes lookalike comparisons to both parents, laughingly musing on the talk show that, "I look like him, I look like her ... frankly, I think they're cool-looking so I don't mind."
