Today is all about amour, and celebrities have taken to Twitter to declare their love to the world and to their significant others. As usual, we were there to stalk their pages and collect these sweet missives to share with the rest of you.

To start us off, Zooey Deschanel tweeted an adorable photo of herself with a couple of furry friends, captioned, "Happy Valentines Day!!!"

Not only is Deschanel herself almost unbearably cute, but when you throw the dogs in… well, our heads almost exploded. Almost. Let's see who else tweeted sweet nothings today:
