Justin Bieber's mom couldn't be more thrilled he's having a baby, baby baby.
After all, Pattie Mallette shared a sweet Father's Day tribute to her son, who is expecting his first child with wife Hailey Bieber.
"Happy Father's Day Justin," Pattie wrote on Instagram June 16. "You've always wanted to be a dad ever since I can remember. You have so much love to give. You're gonna be the best daddy ever. You already are. LOVE YOU!"
In her heartwarming post, Pattie included some pictures from Justin and Hailey's initial pregnancy announcement—including a picture of Justin embracing Hailey's baby bump—as well as a mirror selfie of Hailey showing off her stomach, and a photo of the couple sharing a kiss in matching black jackets.
Justin, 30, and Hailey, 27, first announced they are expecting early last month, sharing Instagram photos from their private vow renewal in Hawaii.
And while the couple kept their announcement simple, only tagging each other's Instagram handles in their pictures of Hailey's baby bump, they've been open about their desire to become parents.
"I'd love to have myself a little tribe," Justin admitted to Ellen DeGeneres back in 2020. "I am going to have as many as Hailey is wishing to push out."
Meanwhile, Hailey has echoed Pattie's sentiments, noting that Justin was upfront about wanting to start a family with her as soon as possible.
"We were having pillow talk conversations, with him telling me my biggest goal in life is to have a healthy family," the Rhode founder explained on a 2021 episode of In Good Faith with Chelsea & Judah Smith. "We always wanted to be married young and have a young family and have kids young."
And with her only child now expecting a baby, Justin's mom has also been open with her excitement about becoming a grandmother.
"I have been waiting for this day," she admitted to her followers shortly after Hailey and Justin shared news of their pregnancy. "I can finally celebrate with y'all. Oh my gosh, I'm gonna be a grandma! Oh my goodness. Justin and Hailey, you are gonna be the best parents ever, and I am so excited."
Pattie may have been waiting forever and a day for her son's road to fatherhood, but Justin isn't the only star who celebrated Father's Day.
