Paulina Gretzky's new Instagram snap makes it seem like she never even got pregnant in the first place. Less than six months after giving birth to son Tatum in January, Gretzky's showing off her insane bikini bod in the new photo.

Professional golfer Dustin Johnson's fiancée definitely made a grand entrance for her return to social media on Wednesday.

The 26-year old is casually "lounging" in a teeny, tiny polka dot black string bikini matching her dark sunglasses while holding a bottle of green juice. Her hair looks amazing too, in a slicked-back half ponytail.

Actually, Gretzky was still smoking hot even as a pregnant momma. In December, she uploaded a photo on Instagram showing off her toned yet beautifully pregnant body. "Merry Christmas Everyone!! Ps.. We're having a BOY," she captioned the photo.

The model and singer probably partially attributes her amazingly toned abs and physique to her mother, Janet Gretzky. On Mother's Day, Paulina posted a snap of her 54-year-old mom clad in a black bikini while catching some rays.

Paulina Gretzky seems to be loving the life of a mom. Just hours after Tatum was born, Paulina posted a snap with Dustin as they cradled the newborn.

The photo was captioned, "Happiest day of our entire lives was welcoming our sweet baby boy into the world 1.19.15"

Paulina's Instagram consisted of selfies and personal photos with friends in the past. But looking at it now, it's all filled with photos of her son and her family.

In another snap, she wrote, "From the moment you came into this world I knew how much you needed me but never realized how much I needed you."

It looks as though Paulina Gretzky is giving other moms a run for their money with her rocking bod.
