When Justin Bieber turned the big 1-8 last week, it was the "Happy Birthday" heard round the world. Not only did the star get a massive wave of attention from his fans and the media -- not to mention a new car worth $100,000 from his manager Scooter Braun -- but he also took his passage into adulthood as the perfect opportunity to spread the birthday love by launching a new line of greeting cards.
Now, Beliebers can spread Bieber fever to their friends and family with the star's official line of notecards. But if you'd rather not pour out your heart inside a card with the Biebs' face splashed across the front, check out the slideshow below for some more celebrity and movie-themed card-spiration.
