Does Demi Lovato have an admirer this Valentine’s Day? She left this mysterious message on her Twitter page, “To whoever left me those valentines on my front porch, I love you! Best v-day gift ever received! ”

Sounds like the work of Joe Jonas. They did just spend time in Walt Disney World together walking around Epcot, taking pictures with Mickey Mouse, and singing their duet “Make A Wave” at a private concert. Plus, after their quick vacation ended, Joe tweeted, “@ddlovato your awesome! I love u bff!”

But alas, Joe is not the cupid culprit…

Frankie Muniz is. Seriously. He replied to Demi’s tweet with a simple “you’re welcome” and she replied “hahahaha I KNEW it was you… ”

My opinion: I seriously do not think Joe has something to do with it, I think it’s just work of some fans.
