The person is perhaps most excited by the news is his mother, Pattie Mallette.

The 49-year-old grandparent-to-be took to her Instagram account to celebrate the welcome news that Bieber and his wife of almost 6 years revealed.

“So, I have been waiting for this day, and now that they have shared it, I can finally celebrate with y’all and say: Oh my gosh! I’m gonna be a grandma! Oh my goodness!” said in a heartwarming video she shared on social media.

“Justin and Hailey, you are going to be the best parents ever,” Pattie went on to say, adding, “I am so excited!”

“BABY BIEBER IS ON THE WAY!! I’m gonna be a GRANDMA!!CONGRATULATIONS @justinbieber and @haileybieber!!” she wrote in the caption for the video. “My heart is so full. What an exciting new adventure. Love you so much!”

This seems to be something the couple has been wanting for a while. In 2019, Justin Bieber made an Instagram post to his wife, writing in the caption, “One day I’ll be doing daddy daughter dates….. not hinting at anything soon I’m not in a rush. I just wanna enjoy you by yourself for a while!”
