Justin Bieber has sent his "precious" little sister a sweet birthday message as she turned 14 on Monday.
The Love Yourself singer, 28, took to Instagram to share a series of snaps of himself and Jazmyn in years gone by.
He captioned the post: "Can't believe im saying this but Happy 14th birthday to the sweetest, most beautiful, precious, little sis a brother could ask for!!
"Love you @jazmynbieber."
Jazmyn and her brother Jaxon, 12, are the star's half-siblings from their dad's previous relationship.
Justin also has half-sister Bay, 3 - with whom dad Jeremy shares with wife Chelsey - and 15-year-old step-sister Allie Rebelo.
The superstar shared three snaps of him and Jazmyn together in total.
In the first, which is the most up to date, Justin is seen sporting a baseball cap backwards and sunglasses, while sis Jazmyn poses with a pout while leaning on his shoulder.
The second rolls back the years with a younger Justin sitting at a restaurant with his younger sibling.
In the third, Justin takes fans back even further and shows off his old floppy locks in a pic in which his smile is beaming as he holds a much-younger Jazmyn.
Friends, followers and famous faces took to the post's comments section to wish the teen a happy birthday.
Among those sending well wishes was the singer's general manager Allison Jamie Kaye who wrote: "Happy birthday Jazzy!!!!!!!!!!!!"
Singer Sean Kingston also commented: "Angel," alongside a love heart emoji, while businessman John Shahidi said: "HBD Jazmyn!"
Over 1.2 million of Justin's followers hit the like button, including Cruz Beckham.
Weeks earlier Jazmyn had shared her own sweet snap and captioned the image: "Fam time."
It appeared as though the image was taken on the same day as Justin's first birthday image.
Alongside the pair was Justin's wife Hailey Bieber as the family enjoyed drinks in the sunshine.
Justin has also previously shared snaps of his sister and touched upon their close bond.
In December, he upload a black-and-white image of himself with wife Hailey and Jazmyn and Allie.
He captioned the post: "My favorite girlsss."
Justin has also been open about the possibility of starting a family of his own in the near future, but Hailey insists the pair will wait until the time feels right.
