Pastrnak and his girlfriend Rebecca Rohlsson have been together since July 2018.
Rohlsson is from Stockholm, Sweden, but now lives with Pastrnak in Boston.
In January 2021, Pastrnak and Rohlsson announced on Instagram that they were expecting their first child together.
The couple uploaded a gender reveal video showing them exploding seven confetti cannons before revealing that they are expecting a child.
The NHL star previously said how happy and eager he was to become a father.
In May, Pastrnak told NHL.com about his enthusiasm for being a father for the first time.
“You come home and you don’t think about hockey at all, obviously you have other priorities.
You are getting ready for baby and we couldn’t be more excited. Not much has been said about home hockey lately and sometimes that’s a good thing you know? Pastrnak said.
“When things are going well, it’s okay, and when things aren’t going well, sometimes you just have to think about other things.
“It was definitely something new for me, but I’m very excited. Family will always be number one and at the end of the day.
“I am grateful to be able to live and work in a job that I love, but at the end of the day it is just a game. [My family] will always be number one. “
