She's one busy gal, but Katy Perry still makes time for charity!
The singer headed back to the UK this weekend, performing a laser light show extraordinaire for the BBC's Let's Dance for Sport Relief.
The event raises money to help vulnerable people in both the UK and the world's poorest countries.
Great cause to come BACK to UK for! Tune in to BBC ONE & watch the FINALE of Let’s Dance for Sports Relief. I’ll be performing Part Of Me!
Srsly, so many lasers!
