We’ll be honest: when Gigi Hadid and Zayn Malik became a thing in 2015, we thought it was just two ‘It’ kids having a fling.

But fast forward to 2018 and here we are, the couple having recently celebrated their two-year anniversary, and their love totally seems like the real thing.

Case in point: Zayn turned 25 years old on January 12, and Gigi couldn’t help but sing from the rooftops about her love for Zayn. In 2018, an Instagram shout-out is the new rooftop.

Hadid posted several candid pictures of her and Zayn, and captioned the post with a heartfelt dedication to the Dusk Till Dawn signer.

“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 wrote.

“Cheers to YOUR YEAR my @zayn – happiest happiest birthday & 25th year of life!

“I’m proud to be by your side.”
