5 Seconds of Summer stopped by today to performed their hit “She Looks So Perfect” for the first time on US radio live in-studio, and we can guarantee that this is going to be the song of the summer!

A little background on the Australian boy band, they started as a group of friends that liked posting covers on YouTube. Their cover of Chris Brown and Justin Bieber’s song “Next to You” has over a million views. After their videos became popular, it wasn’t surprising that major record labels started calling. They even got some exposure thanks to One Direction’s Louis Tomlinson and Niall Horan. They posted links to 5SOS’s original songs “Gotta Get Out” and “Out of My Limit.” Apparently the UK boys have been fans of the Aussies for a while.

Their first EP, She Looks So Perfect, debuted at number two in the US and number one in over 45 countries! Look out for their debut album, which is going to be released this summer. Currently the boys are on their first EVER US tour, which sold out in five minutes in all 10 cities.

5SOS will be on the road with One Direction starting this summer for their North American leg of the “What We Are” tour. In 2012 the four-person band opened for Hot Chelle Rae for their Australian Tour.
