Justin Bieber is apparently feeling nostalgic about his relationship with wife Hailey Bieber. The singer, 31, shared a slew of photos via Instagram on Wednesday, September 17, including one from his wedding to Hailey, 28, and another of her pregnancy with their son, Jack Blues, who recently celebrated his first birthday. Although he didn't caption any of the pictures, Justin posted over 90 images and videos to his social media account - ranging from fan clips to family photos. One throwback image showed him snuggled up to Hailey's bare baby bump as she sat on a couch.
