Sean Ono Lennon and girlfriend Charlotte Kemp Muhl have announced the birth of their baby boy.
After Sean’s brother Julian revealed the news in a now-deleted social media post, the son of Beatles legend John Lennon and Yoko Ono confirmed the happy news on Instagram last night.
Proud dad Sean, 50, posted photos of his baby boy as he told fans ‘Okay so…Charlotte and I would like to announce that we have indeed created a Human Bean! His name is, Aurelius! Thank you!’
Charlotte, 39, also shared her own post featuring life as a family of three and admitted she was feeling sleep deprived. ‘We made a human! Am convinced DNA is agentic alien quaternary code,’ she wrote.
‘The sleep deprivation only adds to the surrealism…Burping technique tips welcome. Been playing him Aphex Twin and Stravinsky. Meconium is crazy.’
Aurelius is the first grandchild of John. Yoko, 93, already has two grandchildren from her older daughter Kyoko.

Hours before his post, Sean’s baby news was broken by his older brother Julian, 63 – the son John shared with his first wife Cynthia.
Julian wrote in a now-deleted Facebook page that he had been enjoying a trip to London last week during which the ‘the most amazing thing happened in the whole wide world, I became an uncle!’
He added his congratulations to Sean and Charlotte ‘and their new “Beautiful Boy”‘, referencing his father’s song dedicated to Sean.
Charlotte is an American musician and writer and she and Sean have been linked since 2007.
Last year Sean shut down rumours of a longstanding rift with Julian by reposting a fan’s post about his relationship with his sibling, who is also a singer and songwriter.
‘Here, we do not accept comparisons and erroneous creations of fights about two people that John Lennon loved the most: his children :),’ wrote a John Lennon fan account, which Sean reposted to his Instagram, who added, ‘Peace and much love.’
The post featured a sweet black-and-white image of Julian, who was around 23 at the time, as he rested his hands on Sean’s shoulder affectionately at the 1986 Rock and Roll Hall of Fame induction ceremony, where both joined in a celebration for the induction of Elvis Presley.
Sean, who would have been around 11 at the time the photo, has been dogged by rumours that he and Julian have been estranged for years, but much of it seems to be driven by social media users expressing distaste for one – or both – of his famous parents.
Yoko and John were still married to their spouses Anthony Cox and Cynthia Powell, respectively, when they originally met in 1966.
Sean was just five years old when his father was shot dead by Mark Chapman outside his New York apartment in December 1980.
Fans have previously highlighted Julian’s past statements criticising his stepmother as evidence of a family split.

Julian previously claimed that he had to buy back letters and postcards he had written to his father – and the ones he’d received in return – because his stepmother had refused to give them to him.
He sued his father’s estate in 1996, eventually reaching a settlement authorised by Yoko.
In a 1999 interview on The Deni Petty Show, Julian witheringly referred to Yoko as ‘her highness’ and noted that the two had a rocky relationship, as she was the executor of his father’s estate.
He feared any criticisms he made about the enforcement of Lennon’s will could result in him being cut out completely.
But in the same interview, Julian made it clear that he had only warm feelings toward Sean, and he claimed his younger brother was only caught in the middle of a difficult situation.

Julian has steadfastly made it clear that he and Sean are loving siblings, even if Sean has been less vocal about their relationship over the years.
In a December 2024 social media post, Julian shared some sweet black-and-white photos of the two catching up at The Dakota, the building in Manhattan where his father lived for years with Yoko and Sean before he was shot down in front of it.
‘A Goodnight kiss for my brother, after spending the evening with him, having a lil dinner & chatting the night away, at The Dakota,’ he wrote. Something we rarely get to do… Thankful.’
Both Sean and Julian have followed their father into music. Sean works as a producer and musician alongside his role as the main caretaker of his parents’ artistic legacy.
Charlotte performs with Sean in the musical duo The Ghost of a Saber Tooth Tiger.
