Not a prank, and very exciting news.

Full disclosure - we're aware that it seems suspicious for a festival to drop an artist announcement on April Fool's Day. We get it.

However, Warped Tour have announced their line-up additions by prefacing their posts with a disclaimer that this is definitely not an April Fool's joke.

Joining the already stacked line-up in Atlantic City will be the likes of The Used and The Story So Far - but sadly Gym Class Heroes have dropped off the festival line-up. That's not totally bad news however, as Travie McCoy is still making an appearance and playing a set! Phew!

And over on the West coast, ONE OK ROCK and Yungblud are set to play the Mountain View date.

Check out the full list of line-up additions below:
