Taking to the photo-sharing app, Demi treated fans to a cute new selfie with her That '70s Show beau. Hinting the pair have made it through another year together, Demi posted a love heart alongside her post, simply adding the caption: "6."
In her photo, the 'Confident' singer can be seen cuddling up to Wilmer in bed and it's fair to say the couple do look pretty smitten.
In another post, Demi shared six photos of herself and Wilmer - one for every year they have been dating.
On seeing her latest Instagams, fans were quick to send their congratulations to the couple for making the milestone.
One follower said: "Both of your eyes look so in LOVE! Such a blessing. Very happy for you both!" While another told the pair they were so lucky to have each other.
Many, meanwhile, couldn't resist asking the couple when they are going to get married.
Clearly hoping a wedding is soon to be on the cards, another fan added: "When are you guys gonna get married already?"
For quite some time now, Demi and Wilmer have been at the centre of engagement rumours, with Demi last denying Wilmer had proposed in June last year.
At the time, she gushed: "He's there for me when others aren't... He supports me when others won't... He loves me when others don't (not engaged... yall are crazy)."
It's only a matter of time, though, right?
