Tammy Hembrow’s one of the OG Aussie influencers … and to celebrate her birthday, we’re flexin’ just how hard she’s still shaping the game with her sizzling snaps.

After all — how could we not celebrate Tammy’s 31st when she’s out here rockin’ bikinis like a boss, showcasing every inch of that gym-honed grind?

As you can see, Tammy’s wardrobe motto seems to be “less is more” — and we ain’t mad at it ’cause she’s out there slaying 2-pieces like it’s a full-time job.

It’s either the gym or the beach for Tammy — and she’s clearly mastered both. From perfecting her angles to topping up her tan, the girl’s got her brand on lock.
