Jodie was joined by the professional bodybuilder in Birmingham today (13 December) during a meet and greet with fans of her JSTJodie line.
The former glamour model, who now sports rippling biceps and muscles - not to mention an incredible six pack, looked pretty in pink as she and Zack posed for pictures.
Jodie teamed her cute jumper with a pair of light blue skinny jeans and wore her dark hair in a slick ponytail. She topped off her look with a pink lippie.
Zack, meanwhile, was wearing a red T-shirt with the Superman logo on the front and wore a massive chunky silver chain around his neck.
The pair had a laugh posing for pictures together, and at one point Zack scooped Jodie up into his arms as they smiled for the cameras.
Jodie became friends with Zack, who is from Sheffield, when she got into bodybuilding and she is often spotted hanging out with him.
In October, the pair enjoyed a holiday together in Las Vegas.
Meanwhile, Jodie took a break during the signing - and got the back of her neck pierced!
She later shared a picture of her new silver body art with fans on Twitter, saying: "So on my break at store signing @gncuk I went and got my neck pierced!!!!! Haha."
Jodie's fans definitely approve, with one replying: "Ha ha good way to take a break :)"
You're a braver girl than us, Jodie!
