WATCH: Katy Perry performs heartbreaking rendition of 'Witness' album track

She performed 'Save As Draft'

This Friday (21st July) one of our favourites is taking over – Katy Perry!

She'll be here, playing all her biggest hits from 'I Kissed A Girl' back in 2008 to her brand new single 'Swish Swish' featuring Nicki Minaj (which we LOVE).

We're pretty obsessed with her new album 'Witness' - it went number 1 in 46 countries! It features the singles 'Chained To The Rhythm' and 'Bon Appétit', so no wonder really.

PLUS, Katy will have your chance to win a once in a lifetime trip to New York to see her live!

Listen this Friday at 2pm. We can't wait

We're super excited to chat with the 'Roar' singer and so to celebrate here are three exclusive tracks that Katy recently performed for us and some of her biggest fans.

Katy chose to sing 'Save As Draft', a hugely emotional track about moving on and struggling not to reopen old wounds with an ex. Anyone who has been through heartbreak is going to relate to this track!

The singer also performed an incredible acoustic version of her huge hit 'Chained to the Rhythm':

Katy also performed the upbeat track 'Hey Hey Hey':

Put it in your diary - 2pm on Friday 21st July! We're also going to have the most amazing Katy Perry competition to tell you about! What an exciting day!
