Katy Perry Covers Queen's 'We Are The Champions' At Summertime Ball 2012

The 'Teenage Dream' star performed all of her biggest hits, including a Queen cover, at today's Capital FM event.

Katy Perry performed a huge headline set at the Capital FM Summertime Ball tonight, complete with a surprise cover of the iconic Queen hit 'We Are The Champions'. 

Katy kicked off her Summertime Ball 2012 set with a performance of her 2008 single 'Hot n Cold', taken from her first studio album 'One Of The Boys', while wearing black and white spotted trousers and matching crop top, along with a red latex jacket. 

"London! How about a 'Teenage Dream' tonight?" Katy asked while breaking out into her smash single 'Teenage Dream', much to the excitement of the 80,000 fans in attendance at Wembley Stadium today.

After leading the crowd through a sing along for 'Teenage Dream' , Katy went straight into her weekend celebration song 'Last Friday Night (T.G.I.F.), striding out to the front of the Wembley stage to get up close with all of the fans on the stadium floor.

"England! Did you have a great time tonight? I'm so happy you saved me for last!" Katy announced. "I have never played here before and this is an incredible feeling. I want you to sing along to this next song, it's called 'Part Of Me'."

The singer then belted out her recent Vodafone Big Top 40 hit 'Part Of Me' , which was released as a single from her repackaged sophomore album 'Teenage Dream' earlier this year.

Surrounded by backing dancers in bright blonde wigs, Katy's energetic performance featured huge amounts of pyrotechnics as well as a polished dance routine right at the front of Wembley stadium.

Katy then introduced new single 'Wide Awake' and performed on stage alongside her band for the song, which serves as a promotional single from her upcoming 3D concert movie Katy Perry: Part Of Me 3D.

She then invited her band members down to the front of the stage for a stripped down performance of 'The One That Got Away', which saw them all raised up on a rising platform.

Katy then shocked the audience with a surprise cover of Queen's signature hit 'We Are The Champions', rousing the Wembley audience up to help her sing the iconic rock chorus.

After performing her 2011 anthem 'Firework' Katy urged the crowd to join in with her final song of the night, her lead 'Teenage Dream' single 'California Gurls' .
