Dame Shirley at the National Portrait Gallery
Dearden's portraits taken at the Glastonbury Festival will be on display for the first time in the exhibition that runs from 19 April until 26 September in the Bookshop Gallery.
Dame Shirley performed in a front of the mud-covered Glastonbury audience in 2007.
She wore a vibrant pink sequinned dress by Merthyr Tydfil born fashion designer Julien Macdonald - complete with matching feather boa and diamante encrusted wellington boots.
Venetia Dearden was born in Somerset in 1975 and has a long affinity with the music festival, having worked at and attended the event from a young age.
This will be the first solo museum display of her photographs.
