Aww, these two!
The pop singer posted a loved-up picture of the That ‘70s Show actor kissing her cheek and wrote, "I never post personal pictures like this but f--k…He is perfect. I miss my @wilmervalerrama."
The rare PDA pic made Lovatics go wild and the snapshot garnered a whopping 500,000 likes within hours of it being published.
The two haven't exactly made it a secret that they're close, and even sparked a frenzy earlier this year when multiple outlets claimed that the actor and former Disney darling were engaged.
However, the songstress' rep told E! News at the time that there was absolutely no truth to the rumors.
And in honor of Valderrama's special day, Lovato took to Twitter to share a heartfelt message about close (ahem, very close) friend.
She wrote, "To the funniest, most inspiring, incredible man I know.. @WValderrama - thank you for helping me get through my darkest moments.. You truly are a light to this world and to my life.. Happy Birthday!!!"
The birthday boy then responded, "who needs presents when the gift of you is real to us all.. Thank you for the blessing of knowing you."
