The 'All of Me' hitmaker and his wife - who have 17-month-old daughter Luna together - have been married since 2013 and this week celebrated their four year wedding anniversary.

And to ring in the milestone, John, 38, took to Instagram to post an adorable snap of himself and the 'Lip Sync Battle' star as they prepared for their date night in honour of the occasion.

He captioned the snap: "Anniversa-date. Married 4 years today. Met 11 years ago yesterday. I love this woman deeply. (sic)"

The couple aren't shy when it comes to showing their love for one another either, as John recently gushed in an interview that his 31-year-old spouse has helped him "develop more empathy".

He said: "[Marriage] helps you develop more empathy. Part of being a good husband and father is being able to listen, be humble and compromise. It's not about dominance and power. You learn as you get older, the best relationships are about give and take."

However, the pair's relationship hasn't always been perfect, as the 'Love Me Now' singer admitted he once tried to break up with the model.

He revealed: "I was really stressed and busy. I was just like, 'I'd just be happier single right now,' and she was like, 'No.'"

But Chrissy later insisted it was not a "typical break up" and that John was just "being a whiny face" at the time.

The Sports Illustrated model tweeted: "It wasn't a typical breakup. He was on tour and his voice hurt and he was being a whiny face about everything and so yeah, I was like 'no' (sic)."
