John Lennon's son celebrates baby boy's arrival

Sean - the son of late Beatles star John and his wife Yoko Ono - and partner Charlotte Kemp Muhl took to their social media pages on Tuesday (01.09.26) to announce the happy news, alongside a picture of themselves with the new addition.

Sean wrote on Instagram: “[Charlotte] and I have created a Human Bean. His name is Aurelius! Thank you!”

Meanwhile, model Charlotte also shared pictures on her Instagram page, as she wrote: “We made a human! Am convinced DNA is agentic alien quaternary code.

“The sleep deprivation only adds to the surrealism…Burping technique tips welcome.”

In addition, Charlotte said she and Sean were already introducing Aurelius to music, playing him music by Russian composer Igor Stravinsky and techno star Aphex Twin.

Upon announcing the arrival of their baby boy, Sean and Charlotte were inundated with messages of congratulations from their famous friends and followers.

Among them, a message from Zak Starkey - the son of John’s Beatles bandmate Ringo Starr - who wrote “Amazing!”

And singer Amanda Palmer added: “You did. You did. I’m so proud of you both and so happy. I remember our conversations. It changes your life in ways I never could have understand. Call any time for joy or commiseration.”

Sean and Charlotte first met at the Coachella music festival in 2005, but the pair didn’t start dating until 2007.

Speaking about their relationship during an interview with MusicRadar in 2010, Sean explained: “We didn’t wind up hanging out for a couple of years.

“We developed our relationship through writing letters, postcards and emails, and it made our relationship stronger in the long run.”

It wasn’t until they’d been together for a year that Sean discovered his other half’s musical talents, after hearing a song she’d written as a child, and they have collaborated on various music projects since - including in the band The Ghost of a Saber Tooth Tiger.
