​Bikini-clad Janet Gretkzy is the ‘hottest grandma’ in Paulina Gretzky’s Mother's Day photo

She may be a mother of five (and a grandmother of one!), but Janet Gretzky can rock a bikini with the best of them. Wayne Gretzky’s eldest daughter, Paulina Gretzky, celebrated Mother’s Day over the weekend by sharing a glamorous photo of her beautiful mom on Instagram.

Paulina – who is a new mom herself after giving birth to son Tatum in January – paid tribute to her gorgeous mama in the snap, which shows The Great One’s wife soaking up the sun in a black two-piece swimsuit.

Janet Gretzy, 54, is one hot grandma

“Happy Mothers Day to hottest mama of 5 and grandma of 1!” she wrote in the caption.

The image prompted a flurry of impressed comments from fans, who expressed envy at the 54-year-old's flawless figure.

“Um what. 5 kids!! And here I am working out everyday to look like this grandma,” wrote one admirer.

“Grandma’s still got it!” enthused another.

Not to be outdone, the 26-year-old blond beauty followed up her Mother's Day post with her very own bikini photo on Monday (May 11). The model and singer bears a striking resemblance to mom in the stunning snap (good genes clearly run in the family!).

Like mother like daughter: Paulina and mom Janet know how to rock a bikini!

In addition to the bikini selfie, Paulina also shared a sweet photo of her and Tatum snuggling along with the following message:

“From the moment you came into this world I knew how much you needed me but never realized how much I needed you. Happy Mothers Day everyone!!! ❤”

Paulina Gretzky's year in Instagram photos

Paulina and her pro-golfer fiancé, Dustin Johnson, welcomed their first child in January. The NHL heiress described the life-changing moment as “the happiest day of our entire lives.”

The pair became engaged in July 2013, but have yet to set a wedding date – though rumour has it that they are contemplating autumn nuptials.
