Justin Bieber and his wife Hailey paid tribute to each other on their fourth wedding anniversary.
The Peaches singer, 28, gushed over his 'best friend' Hailey, with who he obtained a marriage licence in 2018, in a sweet Instagram post.
The happy couple waited until 2019 to have a lavish wedding ceremony with their closest friends and family in Bluffton, South Carolina.
And now, four quick years later, he shared a black-and-white snap of the two cuddling their dog in bed.
"Happy anniversary to my best friend and wifey @haileybieber.. thanks for making me better in every way," he captioned the post.
Meanwhile, Hailey, 25, shared a series of cute pictures on her page, including one from their ceremony.
One picture had her smiling as she leaned on his shoulder while he was driving while another snap was of the two holding hands.
"4 years married to you. the most beautiful human I’ve ever known... love of my life. Thank God for you," Hailey captioned the post.
One of her pictures was of Hailey sitting at the dinner table as she turned her head upwards to give her husband, who was standing behind her, a smooch.
Pals were loving the gushing post and throwback pictures and took to the comment section to congratulate them.
Khloe Kardashian added a few heart emojis while her sister Kim wrote: "I love you guys."
Ireland Baldwin said: "Love your love [heart emoji]," while stylist Karla Welch wrote: "Verified Love u both so much!!!! To a lifetime more."
Their anniversary comes after Hailey revealed that married life with Justin takes 'a lot of work'.

Despite both suffering serious health scares recently, Hailey says she and Justin are still going strong.
“He's still the person that I wanna be rushing back to," the model told Harper's Bazaar as she marked four years since they got engaged.
She added: “I might fly somewhere and go do a job, but I can't wait to come back and hang out."
Hailey praised “the effort that's been put in on both sides” of their relationship – effort which she says got them through ups and downs.
“At the end of the day, like, he's my best friend, but it still does take a lot of work to make it work,” she told the outlet.
“And then I know eventually, when kids come in the picture, that's going to be a whole other season of navigating how to make that work,” she added.
