Sean Ono Lennon has announced the birth of baby boy, Aurelius – with the child becoming John Lennon and Yoko Ono’s first grandchild.
The musician and his girlfriend Charlotte Kemp Muhl announced the birth on social media last night (Tuesday September 1), sharing a photo of the three of them together and saying that they had “created a Human Bean”.
The caption also shared that they had named him Aurelius, and the birth marks the first grandchild of Yoko Ono and John Lennon.
Ono Lennon also posted some other photos of himself and his partner holding the baby, and comments congratulating them have come from Lindsay Lohan, Flea, Paris Hilton, Questlove, Willow Smith and more.
Sean is the only child of John Lennon and Yoko Ono, although he is half brothers with Julian Lennon – who was born from John’s first marriage to Cynthia Lennon.
The two have spoken about their relationship multiple times over the years, with Julian sharing in 2023 that rumours of an alleged feud between them were “such bull” as they had “never had a fight in our life.”
In 2025, Sean spoke out against any rumours of bad blood between them too, asking fans not to compare them as they are “best buddies”.
Julian has established himself as a musician, photographer, author, and philanthropist, and Sean has a successful solo career as well as joining forces with Primus’ Les Claypool once again to release their third album as the Claypool Lennon Delirium.
As well as his own musical endeavours, Sean has also been hands on with many Beatles projects over the years – including producing a remastered version of a 1995 documentary series called The Beatles Anthology last year, and also overseeing the production of a ‘Mind Games’ reissue boxset.
Last year, he opened up about how he is working to ensure young people don’t forget about The Beatles too, telling CBS’s Sunday Morning that while “the world is also the custodian of [his father’s] legacy”, he was also “doing my best to help make sure that the younger generation doesn’t forget about The Beatles and John and Yoko. That’s how I look at it.”
Also in that interview, Lennon provided an update on his mother, who has taken a step back from public life in recent years. “She’s good… she’s 92, so she’s slowed down a lot, and she’s retired. That’s why I’m kind of trying to do the work that she used to do,” he said.
“That’s why I feel a lot of pressure, actually, to do my best, because she set a high standard for the way that she dealt with my dad’s music, and the Beatles stuff.”
Sean has previously opened up about his father’s lasting impact on his mother, saying that she “never has moved on from that relationship”, as well as discussing the “legendary love” between his parents, and opening up about the reasons he believes his father came to “resent” being a Beatle.
“I don’t feel that he’d fallen out of love with music,” he said last September. “I think he’d fallen out of love with a certain kind of fame. I think he’d fallen out of love with having to be a part of a machinery, of a pop machine, you know?”
Earlier this year, Sean helped bring a remastered version of John Lennon and Yoko Ono’s Power To The People concert film to cinemas worldwide.
That film is a document of the ‘One To One’ concerts that the couple held at New York’s Madison Square Garden on August 30, 1972. Only two performances were held, one a matinee show and the other in the evening, and they were Lennon’s only full-length concerts after leaving The Beatles, as well as the last gigs John and Yoko played together.
Speaking about his work to restore the footage, Sean told NME: “It’s been a very long time in the making. The concert was originally filmed in 1972 and for decades the footage was being restored to high quality digital. But I didn’t oversee that process because I know nothing about it. I wasn’t really involved until more recently.”
He also spoke about how his father sounded different in those shows compared to his time with The Beatles, saying: “I think everyone who listens to it gets chills from how good his voice is – and it’s good in a way that is totally un-Beatles. It’s like he’s finding a new way of singing.”
