It's official: we just found another reason to love these two even more. 

After the release of Demi Lovato's highly anticipated music video for her single "Cool For the Summer," her longtime boyfriend Wilmer Valderrama took to Facebook to congratulate the pop star in addition to poking fun at his gorgeous GF in an adorably amusing manner.

Sharing a shot of himself as Fez from That '70s Show alongside a screenshot of Demi, the 35-year-old actor quipped ""Imitation is the highest form of flattery.. Thank you Demi... LOL #CoolForTheSummer video!" 

He also added a series of hilarious hashtags to his post (honestly, we can't stop laughing), "#YouBetterWerk #VictoriaSecret #vogue #SorryNotSorry #FezGotThatSauce #ThighGameStrong #F--kYourThichGap #Pears #IGotItFromMyMommy #MoveBirthGetOutTheWay #BiggieSmalls #NWAIsBack and of course... #Yonce," he wrote of the pic.

The 22-year-old pop star also reposted the pic on her Instagram page with the caption, "The couple who slays together... STAYS TOGETHER #RELATIONSHIPGOALS #MYFEELS #ICANT #YAAAAASSSSS #YONCE #COOLFORTHESUMMER."

Jokes aside, Lovato totally kills its in her latest music video and Valderrama could not be more proud of his stunning ladylove. 

"Hola #Cheeks haha! GAME OVER MAMI! Go TELL YOUR MOTHER a BOSS has arrived #CoolForTheSummerVideoToday: http://vevo.ly/H1lKBv  cc: @ddlovato," the From Dusk Til Dawn star posted, which Lovato also retweeted.  

In addition to providing us with some serious #relationshipgoals, Demi and Wilmer have also been at the center of engagement speculation as of late.

"I am very, very in love with him. I think—we will probably wait a little bit longer, but—if he asked tomorrow I would say yes," the former Disney star recently told a New Zealand radio station. 

She later clarified via a sweet Instagram post that the two are not engaged...yet. 

"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)," she captioned a recent pic of the two holding hands. 

Try and be more adorable, you two! We dare you.
