This Is What Paulina Gretzky Wore To Her Mom's Birthday Party (PHOTOS)

If you were celebrating your mom's birthday with your family, what would you wear?

For Canadian American starlet Paulina Gretzky, the answer would be obvious: A sexy leg-baring, cleavage-enhancing outfit!

The 25-year-old hockey heiress celebrated mom Janet Gretzky's birthday on the weekend (what, no Golden Globes 2014 invitation?) wearing one of the most revealing non-bikini outfits we've ever seen and shared photos of the event on Instagram, natch.

Surrounded by Canadian legend Wayne Gretzky, mom Janet and fiance Dustin Johnson, the Maxim cover girl gave us her best Valley Girl pose wearing tiny leather shorts (which look familiar) and a black bustier top with a low V-neck.

"Happy Birthday Mom @janetgretzky we love you so much!!!" the blond babe wrote, before posting another Instagram snap which showed her flanked by her gorgeous mom (a former Playboy cover girl) and younger sis, Emma.

Janet also posted a few Instagram photos of her own, including a sweet pic of the whole Gretzky clan gathered together which showed Paulina in a surprisingly modest long sleeved, high-neck top.

But we have to ask: Did Wayne approve of his little girl's revealing outfit? And does he know about her No. 99 tattoo?
