Wayne Gretzky is going to become a grandfather soon.

Late Tuesday night, The Great One's daughter Paulina Gretzky—who has turned into a bit of a celebrity in her own right thanks to her singing career and, more importantly, her Instagram account—announced that she's expecting her first child with fiancé Dustin Johnson. She didn't reveal how far along she is in her pregnancy or when she's expecting to have the baby. But she did post this photo on Instagram that features her showing off her baby bump:

"@djohnsonpga & I are so excited to finally share with you all our amazing news," she wrote as her caption for the photo. "we're having a baby!"

Paulina's mom Janet Gretzky also reposted the photo along with the caption, "We couldn't be happier."

Congrats to the happy couple—and to the grandparents-to-be. Guess we know what Dustin will be doing now during his six-month suspension from the PGA Tour, eh?
