Amy Macdonald is one of the first acts to be headlining the Pinktober charity gig.
The Scottish singer will take to the stage with The Bangles and Beverley Knight at the Hard Rock sponsored concert, held at London's IndigO2 on October 5, to help raise awareness and funds for the Caron Keating Foundation.
"I'm really happy and honoured to be supporting such a wonderful cause - and it's great that we can have such a fun-packed evening and raise money at the same time," Amy said.
Beverley added: "I performed a Pinktober show at Hard Rock London two years ago and it's great to come back and continue my support for this fantastic charity."
Tickets for Pinktober - which marks what would have been the late TV presenter's 48th birthday - go on sale on August 11 on www.ticketmaster.co.uk, with proceeds from ticket sales donated to her charity.
