There's nothing quite like watching a video of someone who loves One Direction so much that she can't stop screaming about them for 35 seconds straight.
To celebrate the release of their new album 'Four' -- the 80s-inspired, dad-rock anthem of our dreams -- we've compiled a bunch of photos of One Direction throughout the years.
See One Direction, Justin Bieber, Miley Cyrus, Big Time Rush, Demi Lovato, 5 Seconds of Summer and more celebs react to fans throwing their bras on stage.
It's no secret that a bulk of One Direction's fan base is skewed towards the younger, female demographic. So when One Direction find themselves traveling from city to city on an arena concert tour, you get bet that there will be thousands of screaming fans waiting to get a glimpse of the guys on stage.
And where there are young girls out on their own, not far from them are concerned, disgruntled dads.
One Direction aren't shy about putting their own spin on some of music's biggest songs and while performing in Arlington, Texas, the boys took on Kings of Leon's 'Sex on Fire.'
