Yes, 5 Seconds of Summer have actually touched these. Not with their bums though, unfortunately.
HELLO - we think you might be quite excited in about 5 seconds time - because we've got TWO PAIRS of American Apparel underwear up for grabs to kick off the final week of our 5SOS month on Sugarscape.
Two pairs of American Apparel underwear signed by the 5SOS boys themselves, to be exact.
LOOK HERE THEY ARE, JUST WAITING FOR YOU TO GIVE THEM A HOME.
Ashton, Luke, Calum and Mikey have all scrawled their names across the pants in marker pen, so whether you want to wear them, frame them, or sleep with them under your pillow, it's basically like having a bit of them with you at ALL times.
Also we'd just like to point out that the purple ones are the very same pair Calum wore on his head for our awesome 'Totes Emoji' game (see below).
To be in with a chance of winning this fab prize, you need to do TWO things.
1. Send us a video on either Twitter or Instagram of you dancing to 'She Looks So Perfect' with a pair of pants on your head using the hashtag #Sugarscape5SOS.
Here's our example to give you an idea of what we want.
