Justin Timberlake shares super emotional tribute to Jessica Biel on her birthday

Name a cuter couple than Justin Timberlake and Jessica Biel. I'll wait.

The truth is, it's near-impossible to out-cute the celebrity pair, who have been together for 12 years, and married for almost seven now. Case in point: Justin's heartwarming tribute to his wife on her 37th birthday.

The Say Something singer took to Instagram yesterday to name the actress "the most wonderful human he has ever met" and tell the world that he cherishes every single moment with her.

Uploading five pictures of the two of them throughout their time together, Justin wrote: "My partner in this thang called life... you are the most wonderful human I have ever met. You make me smile, laugh, and love life more than I knew I could. I cherish every moment with you and can’t wait to spend so many more years doing the same... but, new. Happy Birthday, you GOD OF ALL SMOKE SHOWS!! Love, Your Huz".

If that wasn't enough for fans, Jessica turned to the comment section to reply, putting: "You make everything feel new, baby. Thank you for always making time for us, and me, amidst this crazy world. You are truly my north."

Seriously, how sickeningly loved-up can these two get?

The pair first met in 2007 at the Golden Globes, with Jessica's 7th Heaven co-star Beverley Mitchell claiming: "I was there like the moment the love connection happened. I was like, 'OK, this is happening.' It was very, very sweet. They were definitely flirting. They were really cute."

Justin was besotted from the get-go, asking a mutual friend if he could call her soon after. "I did it the old fashioned way — by telephone," he said in 2012. "I had to be pretty persistent in order to get her to say yes. But I have a fair amount of tenacity and if I want something I stick to it. And in the end, she agreed."

The couple were separated in their early days together due to Justin's tour, with Jessica admitting that things moved incredibly slow on The Late Late Show With James Corden.

"We didn't kiss for a very long time because he was on tour, and we were talking on the phone, like normal pre-teens do," she explained. "We were just chatting on the phone for hours. So, we never really kissed for a very long time."

Even then though, she said she knew early on that he was the one; the Sinner star revealed she still keeps an email she sent to her producing partner around that time that said: "I will marry this man."

Their long distance phone calls started a beautiful relationship, however, it wasn't all fun and games. In 2011, the two broke up for three months. The Cry Me A River star opened up to Vanity Fair at the time, stating that, although they were separated, she was still his number one.

"She is the single-handedly most significant person in my life. In my 30 years, she is the most special person, O.K.?" he said.

Thankfully, the two sorted out their differences and were back together later that year. In 2011, Justin proposed to Jessica in Montana and they married in October 2012 in Italy. They welcomed their son Silas in 2015, and have been delighting fans with doting Instagram posts ever since.

And they say Hollywood marriages never work! Keep on being adorable, Justin and Jess!
