Bruce Springsteen is donating a piece of original artwork to raise funds for the Jack & Jill Children's Foundation.
He and his wife Patti are joining 1,600 artists to help raise money through a public sale.
The initiative sees people pay €50 for a piece of art on a first-come-first-served basis.
However no one will know the identity of the artist until after they buy it.
The singers are in good company joining U2 frontman Bono, Vincent Devine, Paul Costelloe, Abigail O'Brien, Mick O'Dea, Maser, Laura Cronin and Peter Curling.
There will be a total of 2,600 original artworks for sale in the Incognito collection.
This year's sale will take place in Dublin's Sol Gallery from April 24th to 26th, with previews from the 22nd.
The collection also travels to Cork - and the sale will take place in the Lavit Gallery on May 22nd and 23rd.
Organisers say lots more names are still be announced.
Now in its fourth year, the art initiative has proven to be a huge success - with last year's event raising over €120,000.
Every €16 raised funds one hour of specialist home nursing care for over 340 children.
Jack & Jill funds and delivers specialist home nursing and end-of-life care to very sick children across every county in Ireland, keeping families together at home.
The children are aged from birth to five years, with complex medical needs.
The foundation says research has shown they do much better at home.
The charity must raise over €3.5m every year to fund its home nursing care and respite service.
