Ellie Goulding has praised Katy Perry after supporting the singer on her recent California Dreams tour.
The singer replaced Jessie J as main support for Perry on the US leg of the tour after he London singer was forced to cancel several gigs due to a broken foot.
She told MTV: "I watched Katy's show and was just like, 'Oh my goodness'. I was just blown away by everything.
"It's really nice to hear my songs in a stadium when they perhaps wouldn't be at this point. It's not often that I hear my songs so epically big and loud. I can pretend to be a rock star for a night."
Goulding is currently working on the follow-up to her 2010 debut Lights.
