Apparently it's difficult even for celebrities to recreate Hollywood's perfectly choreographed kisses in real life.

These photos contain some of the worst kisses we've ever seen, and have us reverting to our sixth grade mindset and shouting:

"OMG, you guys, get a room!"

Whether the following celebs are using too much tongue, just want attention or look as if they're wiping the drool off their lips -- these photos are proof that everyone needs to rethink their PDA moments a little more.

Which celebrity pairing earns top honors when it comes to the worst kiss? You decide.
