Demi Lovato & Wilmer Valderrama Go Way Back & There Are Pictures To Prove It — PHOTOS

To be honest, I sometimes completely forget that Demi Lovato is dating Wilmer Valderrama. Maybe it's because they don't overdo it with the PDA. Or maybe it's because they don't make tabloid headlines every other day for breaking up and getting back together. Either way, every time I do remember, I'm very much a fan of this couple. Especially because Lovato has talked about how he's been a huge support system through tough times. On Friday, Demi Lovato shared a #FBF (or Flashback Friday) photo with Wilmer Valderrama. The caption will melt your heart:

#FBF to 4 1/2 years ago and yet all this time later... I still cry when I leave him for tour and I still get butterflies just thinking about him. You're magical Wilmer... I love and miss you...

How sweet is that?! Plus, isn't it crazy to think that Lovato and Valderrama have been together for more than four-and-a-half years? As someone who sometimes forgets they're dating at all, it's almost mind-blowing that they've been together so long. But of course, good for them and it's wonderful to see Demi so happy! The fact that she still gets butterflies around him is equally aww-inducing.

To continue the trip down memory lane, I've rounded up even more photo evidence of how great Wilmi (or Demmer?) are together. Also, important question: Do they actually have a couple name? Because the two options I suggested weren't the greatest... Ponder that as you look through all of these cute pictures!

Support System

To mark three years of sobriety, Demi shared this photo and explained how Wilmer has been there for her through it all.

Valentine's Day

Of course these two spent Valentine's Day together. And they looked great while doing so.

Birthdays

In case you really want to be reminded just how long they've been together, look at this collage of birthdays by the year.

Selfies

This selfie is ridiculously cute, right?

Halloween

Their Lucy and Ricky costumes are picture-perfect.

Matching PJs

Wilmer's b-day message to Demi was incredibly sweet. The matching penguin pajamas make it even better!
