Paulina Gretzky leaves very little to the imagination in a post-baby bikini shot she shared a couple of days ago on Instagram.

Just five months ago Gretzky gave birth to son Tatum, and she doesn’t look even remotely like she was ever pregnant.

Showing off what has to be the most taut and toned post-pregnancy body ever, Paulina Gretzky clearly comes from sexy stock. Last month she shared an Instagram, photo of her 54-year-old mom, Janet Gretzky–wife of pro hockey player and coach Wayne Gretzky, who still looks beyond amazing in a bikini, too.

Paulina Gretzky captioned her own Instagram bikini shot, ‘Lounging.’

And then when posting the photo of her mother, Paulina Gretzky’s caption reads, “Happy Mothers Day to hottest mama of 5 and grandma of 1 @janetgretzky.”

Moms everywhere would likely love to have the good genes that have at least helped Paulina Gretzky and her mother achieve their sexy bikini bodies.

Wow! @PaulinaGretzky shares an incredible bikini photo just 5 months after giving birth. http://t.co/CSkXeUKwf9 pic.twitter.com/WDxwm8tr5F

Do you suppose there’s been at least a little bit of diet and exercise involved in achieving these results?
