Brian Austin Green is enjoying quite the special day as he and girlfriend Sharna Burgess celebrate his first birthday since they started dating.

Sharna took to Instagram on Thursday, July 15 to post a birthday tribute marking the Beverly Hills, 90210 alum turning 48 years old. She shared a carousel of pics that included one of Brian lounging in a hot tub, along with a few throwback pics from when he was much younger that his mom had passed along.
