"@djohnsonpga & i are so excited to finally share with you all our amazing news..we're having a baby!!," she wrote late Tuesday, referring to her pro golfer fiance
Dustin Johnson in the caption on a picture showing her cradling a decent-size baby bump.
The 25-year-old's growing midsection is quite a departure from the ultra-lean, body-licious look she sported on the cover of Golf Digest earlier this year. That sex-sells cover, by the way, ruffled some feathers because her only connection to the game is her fiance. She was Maxim's cover girl last December.
Paulina Gretzky and Johnson, 30, met after he and her mom played together in a pro-am tournament in late 2011 and mama invited him over for dinner afterward, the model told Golf Digest in May. They got engaged in August 2013 but have yet to marry. Plans for a wedding this fall were put off.
"We wanted so badly to do it this fall," she told the mag, "but with his schedule and all it's been hard to set a date. It'll be our special day, and we just want it to be right and to fit."
However, an alleged talking-to by Wayne Gretzky might have played a part as well.
The reputedly hard-partying golfer took a leave of absence from the
PGA Tour starting in August, with a source telling Golf magazine that he'd tested positive for cocaine. While the initial report said he was serving a six-month suspension, the tour later said Johnson's decision was voluntary.
Wayne Gretzky had previously talked to his future son-in-law about shaping up and had offered help, a source told Fox411. Essentially, papa Gretzky's message was clean up your act or the wedding's off, the source said.
The retired hockey star reportedly read his daughter the riot act back in 2011 after her over-the-top selfies -- there's a reason she has 300,000 Twitter followers -- got a little too sexy.
