Paulina Gretzky shares adorable first video of baby Tatum laughing

Love-struck Paulina Gretzky continues to dote on baby Tatum, sharing the very first video of her three-month-old son with fans this week. Wayne Gretzky’s eldest daughter can be heard laughing with delight behind the camera, as her adorable baby boy beams up at his proud mamma and giggles.

“Can’t get enough of this lil guy,” Paulina captioned the super-cute Instagram video, while also tagging her pro-golfer fiancé, Dustin Johnson.

The 26-year-old model and singer welcomed her first child with the 30-year-old athlete in January. The NHL heiress would later describe the life-changing moment as “ the happiest day of our entire lives.”

"It's just unbelievable,” the blond beauty gushed to reporters after Dustin won the prestigious Cadillac Championship last month, where she and baby Tatum had watched daddy from the sidelines.

Dustin's the best dad, he's my best friend. He's been so supportive with me and we're just there for each other. I couldn't be happier for him."

Dustin also explained how becoming a dad had changed his life for the better.

“It's hard to describe, but just from the first day he's born, your perspective on life completely changes,” he said. “It kind of makes life a lot easier, I think, just because there's just one thing that's kind of all you think about. It definitely simplifies stuff."

Life has certainly been on the upswing for the young couple ever since they announced they were expecting last year. After taking a leave of absence from golf, Dustin is back in the spotlight and playing better than ever. Meanwhile, Paulina – who floods her Instagram feed with baby photos – couldn't be more thrilled to be a first-time mom.
