Unforgettable French Montana Feat. Swae Lee Download 'Unforgettable' on iTunes
There might be 5 Seconds of Summer, but what other numbers are tied to our favourite Aussie boys?
The number of countries 5SOS' debut album went to #1 in. NO BIGGIE.
The amount of Twitter followers the band has between the four of them. We're not jealous at all.
The combined ages of 5SOS. Yep. 74. We'll let you do the maths on that one.
How many years it's been since 5SOS was born as a three piece with Luke, Michael and Calum. Then in December 2011, a certain Ashton Irwin joined the party. Picture: Rex
The number of mental hair colours Michael Clifford's rocked (but by the time we've written this sentence he's probably had about four more).
How many awards 5SOS have won in the space of a YEAR. Not to mention a whopping 62 nominations overall.
The combined height (in feet) of all four lads. Although it's rumoured at least 10 foot of that height is down to Luke.
How many Big Top 40 Number 1s the lads have scored. We wonder if they'll be able to make it a hat-trick once 'Good Girls' is released? Picture: PA
How many fans will be watching 5SOS smash the O2 at the #CapitalJBB this year. We cannot WAIT.
The number of dates on the boys' 'Rock Out With Your Socks Out' 2015 headline tour.
How old Calum Hood says he was when he had his first kiss. We find that PRETTY hard to believe.
The number of musical heroes 5SOS have had support from. Dave Grohl, Gerard Way and the band All Time Low have all reached out to the band, causing a serious amount of fangirling from the boys. Picture: Twitter
The amount of dates 5SOS supported One Direction on their 'Where We Are' stadium tour. IMPRESSIVE. Picture: Instagram
Freaking adorable mums! (Sorry, we couldn't resist - the 5SOS mums make our lives). Picture: Twitter
You knew that was coming, didn't ya?
