While performing at Capital FM's Summertime Ball last week in London, the guys of 5 Seconds of Summer got the crowd riled up by performing a familiar hit: Katy Perry's 'Teenage Dream.'

The Australian pop punk band put their own spin on Perry's 2010 No. 1 hit single in front of a crowd of screaming fans at Wembley Stadium. The boys -- Michael, Luke, Calum and Ashton -- have been known to play familiar hits for their fans, as they also covered Green Day's 'American Idiot' in concert as well.

5 Seconds of Summer is hard at work gearing up for their first studio album, which will be released on July 22. The band has already scored a hit with 'She Looks So Perfect' and is looking to duplicate their success with 'Don't Stop.'
