Paulina Gretzky Flaunts Her Baby Bump In Sexy Workout Outfit

Pregnancy certainly becomes Paulina Gretzky!

The 25-year-old mom-to-be posted a cute Instagram snap of herself over the weekend, which showed her flaunting her growing baby bump in a sexy workout outfit.

Wayne Gretzky and Janet Jones' eldest daughter looked gorgeous in a revealing black tank top and sheer black leggings while sitting cross-legged in her personal gym.

The Maxim cover gal didn't caption the pic but her expression said it all. A hint of a smile crossed her face—which looked gorgeous without makeup—as her hand cupped her belly.

The model, who is expecting her first child with fiance Dustin Johnson, has seemingly ditched her partying ways for a more laidback lifestyle, as evidenced by her serene Instagram photos that have showed her taking it easy and forgoing makeup. She's also been spotting flaunting her changing figure and was photographed wearing Lululemon short shorts and a matching grey top.

Although we don't know whether Paulina and Dustin have set a date for their wedding, we're sure that the Golf Digest cover girl will make a beautiful bride.

She's come a long way:
