Photo of Mick Jagger's 1-year-old son sparks fan meltdown: 'Happy birthday... my beautiful Devi'

Sir Mick Jagger's youngest son Deveraux Octavian is one year old and to celebrate the occasion, the Rolling Stone singer's former lover shared the most adorable picture of young Devi on her Instagram.

"Happy 1st birthday to my beautiful Devi!" the rocker's ex-girlfriend Melanie Hamrick shared alongside a sweet snap of their only child, whose striking blue eyes unfailingly remind us of a young Jagger.

The iconic singer-songwriter dated Hamrick – a ballerina with the American Ballet Theatre – back in 2014, shortly after the death of his partner of 13 years, L'Wren Scott. Although Jagger and Hamrick never got married, the couple welcomed a baby boy two years later, whose picture was recently shared by the mum-of-one in a rare Instagram post.

No sooner had Hamrick posted the picture online than fans rushed to the comments section to gush about Jagger's eighth and youngest son.

"Cutest little rock star," one fan commented. A second user shared, "Isn't it crazy how fast the time goes by?! Congratulations on making it through the first year! He is so handsome!"

"Yay!!! What a handsome troublemaker! Can't wait to eat some cake with him," another fan wrote, gushing over young Devi's heartwarming snap by the side of the refrigerator.

Some other fans couldn't help but point out the striking similarities between the father-son duo. "Mick's eyes," a fan shared, as another chimed in, reminiscing: "Awww. Where did the blonde hair and blues eyes come from!? So adorable happy birthday Devi!!"

In June 2017, Jagger's ballerina ex had opened up for the first time about her relationship with the English music star and her son, six months old at the time.

"I definitely don't think of myself as a 'baby mama'. Yes, in the technical sense, I'm not married to the father of my child. But I am in a great, wonderful relationship with him," said Hamrick, according to Mail Online.

She added, "I dance with one of the most well-known ballet companies in the world. To be put in that category is a little insulting. And it's insulting to my boyfriend." The dancer is 43 years junior to her then rockstar boyfriend.

However, by October 2017, Jagger was linked to Kuwaiti-American film producer Noor Alfallah, 52 years his junior. Reports even claimed that the pair spent a "romantic few nights" in Paris.

"Mick still has his legendary charm but even the band were surprised that someone as young and beautiful as Noor came to Paris to see him," a source told celebrity news website.

"They are both single and seemed to have a lot of fun together, so everyone just let them get on with it."
