Hailey Baldwin is getting along just fine with her mother-in-law!
“What a gift!” Mallette, 43, wrote adding a heart-eyed emoji.

“Love you,” Baldwin, who secretly married Bieber, 24, at a New York City courthouse in September, commented on the post.
Earlier on Tuesday, the newlyweds were spotted out in Los Angeles wearing matching pink ensembles.
Bieber sported a pink hoodie paired with black sweatpants and Vans. Meanwhile, Baldwin rocked a pink tracksuit, white sneakers and pulled her newly dyed pink tresses into a sleek bun.
Although the couple officially tied the knot a few months ago, they plan on having an intimate ceremony for friends and family — but they’re in no rush.
“They’ve been figuring out the perfect time to do it, and they both feel like the sooner, the better,” a source close to Bieber told PEOPLE. “They’re still figuring it out.”
Bieber and Baldwin initially eyed a January bash but will likely push to a later month.
“They’re working with the schedules of all their friends and family to make sure they can be surrounded by the people they love,” adds the source. “There’s no real rush. They’re already legally married, but they’re very excited about throwing a celebration with their loved ones.”
The once on-and-off couple — who previously dated before a messy 2016 breakup — rekindled their relationship this summer, before Bieber proposed to Baldwin in the Bahamas on July 7.
