Jessie J Wants Katy Perry Collaboration: "Me And Katy Will Work Together" - Video
The 'Domino' stars talks with Capital FM about being a huge fan of the 'Firework' singer.
Jessie J says she loved getting to hang out with Katy Perry backstage at the Capital FM Summertime Ball 2012 yesterday (9th June) and says the two will hopefully collaborate one day down the line.
The 'Who You Are' singer performed a crowd-pleasing set at the ball this weekend at Wembley Stadium and says she is a big fan of 'California Gurls' star Katy, who closed this year's Capital FM event with a powerful set of all her biggest hits to date.
"I have actually [seen Katy], we hung out a bit," Jessie told Capital FM at the Summertime Ball yesterday. "I went round and saw her and we sat in her dressing room for a bit.
"I definitely think me and Katy one day will work together," the 'Domino' star teased. "I hate saying that, because then it's like 'Jessie J and Katy Perry guarantee to write an album', and it get's exaggerated."
She added: "But, no, she's an amazing artist and I'm a huge fan, and she's always been supportive of my career, so who knows?"
Jessie J's performance at the Summertime Ball saw her entertain the crowd with hits like 'Do It Like A Dude' and 'Who You Are', as well as being joined on stage by surprise special guests Rizzle Kicks for 'Price Tag'.
