Sometimes, even celebrities like to forget the rules of PDA and indulge a little. And behind the curtains of a photo booth, they can do just that. The photo booth gives these famous couple's the chance to relax a little and give in to the idea that they can kiss each other and no one will see and judge them. But every once in a while – either because the celeb decides to share the picture themselves or someone else does it for them – fans get lucky and catch glimpses of these cute photo booth pictures.

And some like Justin Bieber and Selena Gomez's smooch at the Vanity Fair Oscar After Party – their first ever public event as a couple– become so infamous, that they are still used to give fans hope of a reconciliation between the two. And although some of these couple are not together today, their photo booth kissing session will live on forever.
