The 'Cool For The Summer' singer and her beau have been dating for several years now and often find themselves at the centre of reports they are headed for the aisle.
But taking to Instagram yesterday, Demi proved wedding bells aren't just around the corner for herself and Wilmer, telling her followers they were "crazy" to think so.
Sharing a photo of herself and That '70s Show actor Wilmer holding hands, Demi paid a sweet tribute to her boyfriend.
She told fans: "He's there for me when others aren't... He supports me when others won't... He loves me when others don't."
And just to reiterate the loved-up pair won't be tying the knot anytime soon, Demi added: "(not engaged... yall are crazy.)"
Well, that's told us then!
The 22-year-old and Wilmer have been together since 2010 and proving she is still just as smitten with her other half, Demi recently admitted she is "so in love, it's ridiculous".
Demi's dismissal of engagement rumours circulating her relationship comes after she recently released her new single 'Cool For The Summer'.
Just 24 hours after releasing her new track earlier this month, the starlet found herself at the top of the US iTunes charts.
And while she wasted no time in celebrating her recent music success, Demi did tell fans she had hoped boyfriend Wilmer was on hand to join her.
"What a f****** AMAZING DAY," she said. "Seriously one of the best days of my life... Only thing missing was my man... I love you @wilmervalderrama."
