This is just adorable!

You'd be forgiven for thinking that singer Demi Lovato was a single gal, as she very rarely speaks about her love life. In reality though, the star has been dating That 70s Show actor Wilmer Valderrama for four years. The pair are both very tight-lipped about the relationship, speaking only occasionally about each other in interviews.

We appreciate that every couple needs their privacy, but we're still a little bit delighted that Demi chose to share a romantic picture of her beau on social media yesterday.

She posted this sweet PDA snap to Twitter and Instagram with the caption, "I never post personal pictures like this but f—k.. He is perfect. I miss my @WValderrama."

We bet that had Wilmer blushing!

Although Demi rarely mentions her boyfriend online, she has been posting a couple of pictures of late, including this fun Halloween pic, showing the pair dressed as Lucille Ball and Desi Arnaz:

She also mentioned Wilmer in a recent interview, describing him as "my very best friend in the whole world who I happen to be attracted to." 

Aaaaw! ​
