Mick Jagger's Fiancée, 38, Shares Birthday Picture of Him with His Son, Deveraux, 8, Sparking Buzz

The legendary rocker rarely shares glimpses of his youngest child, making the recent birthday tribute from his fiancée all the more special.

Fans couldn't help but gush over the striking resemblance between Mick Jagger and his youngest son, Deveraux Octavian Basil, after the Rolling Stones frontman's fiancée, 38-year-old Melanie Hamrick, shared a birthday photo of the two.

In the final image of Hamrick's Instagram carousel celebrating Jagger's 82nd birthday, the father-son duo sit side by side, both dressed in matching blue sweaters with playful bunny ears perched on their heads. Jagger and Basil's open-mouthed grins mirror each other as they sit at a table adorned with fruit.

In the Instagram post, Hamrick also included two photos of herself with Jagger, capturing quiet moments between the longtime couple as part of the birthday tribute. She kept her caption simple and sweet, writing, "Happy Birthday!!!!🎊 ❤️🥳."

The post received plenty of cheerful birthday wishes for Jagger, but what truly stood out were the comments about the striking resemblance between him and his son.

One admirer celebrated the moment with a nod to nostalgia and rock 'n' roll: "His son looks so much like young Mick. Happy birthday 😎☮️🎂🎉🎁." Another observer pointed out, "Dev looks so much like his Daddy. Out of all his kids this guy is a mini Mick! So adorable."

Someone else chimed in with delight, "His little twin how cute!!!" Another person echoed the sentiment, "I think Deveraux is his Dad's doppelgänger. I sense he will carry on The Jagger legend."

More people gushed, "The last photo is almost a before and after dev looks just like daddy! how beautiful! happy birthday to my favorite legend! and may there be many, many more! ❤️ [sic]."

Another person commented with enthusiasm, "He looks just like Mick!!! So cute." Some followers focused on a specific feature. One simply wrote, "Dad's mouth." And another was quick to agree, "He has his Dads mouth for sure 😲." And someone else couldn't help but note, "Love the bunny ears 🐰👌🥰."

The boy, whom fans say bears a striking resemblance to the singer, was born on December 8, 2016. At the time, Jagger's publicist confirmed the news, announcing that Hamrick, who was 29 and his girlfriend then, had given birth to a healthy baby boy in New York.

The publicist's statement noted that Jagger had been present at the hospital for the birth and that both he and Hamrick were delighted by the arrival of their son, Basil. It also mentioned that the mother and baby were doing well and asked the media to respect the family's privacy.

The new addition marked Jagger's eighth child — joining his seven older children, whose ages range from 26 to 53.

Jagger began his relationship with Hamrick in 2014, following the death of his longtime partner, L'Wren Scott, with whom he had shared 13 years. Over the years, the music icon has welcomed children with Marsha Hunt, Bianca Jagger, Jerry Hall, and Luciana Gimenez Morad.

In addition to his eight children, he is also a grandfather to five and became a great-grandfather in May 2014 when his granddaughter Assisi, Jade Jagger's daughter, gave birth to a baby girl.

Aside from his resemblance to his youngest son, Jagger's relationship with Hamrick also garners public attention, especially because of the 44-year age gap between them.

Hamrick has been open about how little this age gap between her and Jagger affects her. In an interview, she addressed the topic directly, brushing off criticism with confidence. "I don't think about it," she said, adding that focusing on other people's opinions only creates unnecessary problems.

For her, the well-being of those closest to her matters most. "Am I happy? Yes. Are the people in my life happy? Yes. Am I hurting anyone? No. OK, they can mind their own business," she declared.
