We're already loving Katy Tiz's 'The Big Bang' music video (not to mention her acoustic version of the track) so we couldn't wait to see a little behind-the-scenes action of the filming of the vid, which she has shared exclusively with PopCrush.

“If I could delete it all, just so I can do it again, I would!" Katy tells PopCrush about shooting the music video. "Because that was bloody fun!”

"I'm loving the way I've completely changed into a different person [in the video]," Katy continues in the behind-the-scenes clip, which you can check out above. "So, come take a look around, enjoy it -- and there's tons of coffee upstairs," she jokes.

While the snippet is short but sweet, it shows some pretty cool footage from the shoot, including the actors joking around in between takes and the images from the video as the camera sees them. And, of course, it features Katy at the end asking if they can do it all over again.
