Mick Jagger celebrated his 82nd birthday with a very special guest - his young son, Deveraux! Jagger's partner, Melanie Hamrick, shared a series of photos via Instagram in honor of the "Moonlight Mile" singer's birthday on Saturday, July 26. The final snap also featured a rare pic of the pair's young son, who is 8 years old. The photo features a smiling Devereaux and Jagger, who were wearing bunny ears and seated in front of bowls of fruit and a basket. The pair were also seen wearing blue shirts and sweaters, and making the same wide-mouthed and entertained expression.
