When they're not cosying up on the red carpet giving us ultimate #relationshipgoals, or gushing about their marriage in candid interviews, Justin Timberlake and Jessica Biel love nothing more than to profess their obsession with each other on Instagram.

And, erm, can you blame them? Just look at these two!

So, it comes as no surprise that The Sinner actress has just posted the most adorable pictured of the pair on her Instagram to wish her husband a happy 37th birthday. The picture comes days before his performance at the 2018 Super Bowl on Sunday 4 February.

'A picture says a thousand words. And thank goodness because there aren't enough to express ALL the aspects of my love and respect for you,' she captioned the post.

'I'm here, right by your side, OG fan girl #1. Happy birthday, my beloved. Now go crush it this weekend at SB LI.'

Man, that's some deep stuff.

The 'Filthy' singer is set to perform at the Super Bowl LII Halftime Show on Sunday in Minneapolis but had time to celebrate his birthday with a dinner party at the French bistro Meritage in St. Paul, Minnesota, last night.
