This is too cute!

Demi Lovato took to Instagram on Monday to share a personal picture with boyfriend Wilmer Valderrama.

The "Heart Attack" singer, who usually keeps her personal life private, especially when it comes to relationships, posted a selfie of her being kissed on the cheek by "That 70's Show" star, Wilmer Valderrama, who she has been dating on and off since 2010, according to MTV.

"I never post personal pictures like this but f**k.. He is perfect. I miss my @wilmervalderrama," she captioned the post, which has received over 650,000 likes since it was made public.

Valderrama responded to Lovato's post by sharing a sweet video on Instagram of him smiling and winking into the camera while driving his car as Alicia Keys' "Unthinkable" plays in the background. The "From Dusk Till Dawn" star captioned the video, "Dear @ddlovato....."

The back and forth exchange of affection continued when Lovato posted a series of Tweets, which seemed to be about Valderrama, writing, "My heart has completely melted. Going back to sleep now... Life is so incredible. I really am the happiest woman on the planet right now."

You can practically see the stars in their eyes!

 Dear @ddlovato.....
