The couple commemorated the occasion in a HUGE way: they went skydiving together! Gregg shared a video from the experience he surprised Bella with, and it is insane!
Bella shared a cute video on Twitter to tell Gregg how special he is to her.
"Well, I've told you this many times, but you're a very special girl. I can't believe it's been a year already but thank you for making it such a special one ps. I Love You," Gregg posted on Instagram along with a cute Polaroid pic of the pair.
