Jack Blues Bieber has officially taken one trip around the sun.
Hailey Bieber paid tribute to her son with Justin Bieber on his first birthday with some heartwarming photos of them together Aug. 22.
In the first snap, Jack climbs all over Hailey while wearing a diaper as she wraps her hands around him and laughs. In the second picture, the Rhode founder cradles her son in her arms as she gives him a kiss on his forehead. The mother-son duo wore matching white t-shirts for the photo shoot, with Hailey pairing hers with a classic pair of blue jeans.
"1 year of you my beautiful boy," she captioned the Instagram post. "Happy 1st Birthday Jack Blues, you are joy personified."
The 28-year-old also gave fans a peek at Jack's first birthday celebration, which included a lot of balloons.
In the first photo posted to Hailey's Instagram Story, Jack could be seen wearing a striped ensemble as he played with toys in his play pen while covered by white and gold balloons.
The second snap gave a better look at Jack's first birthday decor, which also included baby blue balloons that said "1st birthday" on them.
Jack's milestone birthday follows a difficult year for the Bieber family, during which they have been plagued with incessant rumors about the state of their marriage.
Hailey shed light on how she's been handling the tough times as she simultaneously navigates her first year of motherhood.
"Being postpartum is the most sensitive time I’ve ever gone through in my life, and learning a new version of myself is very difficult,” the model told Vogue in March. “And to be doing that all the while going on the internet every day and people being like, They’re getting divorced and They’re this and They’re not happy: It is such a mindf--k. I cannot even begin to explain it. It’s a crazy life to live.”
"He's my priority," she added at the time. "He is the most important thing to me."
