Gigi Hadid and Zayn Malik have been couple goals since they started dating in late 2015. The pair openly talk about their love for one another , and it seems as though things between them are as strong as ever as Hadid wears her heart on her sleeve in a sweet new birthday message to her BF.

“Love this man more than I could ever put into words, and am inspired by his drive to be and do better every day,” she captioned a cute series of photos of the two. Two of the pics are selfies of the couple snuggling and sharing a kiss, and she also incuded a boomerang and a photo of Malik with his beloved horses.

“Cheers to YOUR YEAR my @zayn, ” Hadid concluded her heartfelt post. “Happiest happiest birthday and 25th year of life!! I’m proud to be by your side x.”

Along with being candid about how much they mean to each other, Hadid has also publicly supported her musician boyfriend when he’s shared his struggles with mental health. In 2016, when the former One Direction member canceled his first-ever solo show due to a particularly difficult bout with anxiety, Hadid stood behind him on social media .

“Z, I’ve seen the battles you go through and the way you fight to get to a place that allows you to get up there for your fans,” she wrote. “Your bravery in those times makes me proud, but your honesty last night proved what you’re all about, being human…Love you and so proud of you always.”

In April 2017, Malik sent Hadid a little birthday love of her own , posting a PDA-filled pic and calling her his “everything.” These two! Happy birthday, Zayn!
