With campaigners Ali Hewson and Adi Roche at the helm of the event, it came as no surprise that last night's launch was one of the hottest tickets in town.
And celebrities -- even the more reserved -- were happy to cosy up for such a worthwhile event.
Jordan and Eve Hewson -- Ali and Bono's two eldest daughters -- were there to support their mum. Jordan (23), who is rarely photographed, posed with her younger actress sister Eve (21). This was a trip home for both young women who are based in the US.
Grainne Seoige, who was MC-ing the event, beamed as she posed alongside her long-term boyfriend, South African rugby coach Leon Jordaan.
Model Holly Carpenter and Leinster rugby star Cian Healy looked relaxed together, while Lisa Fitzpatrick and her husband Paul were happy in each other's company. Morah Ryan was also there with her eldest daughter, TV presenter Lottie.
And 2fm star Tubridy was there, as was his on-off girlfriend Aoibhinn. The pair didn't pose for a photograph together, although both happily attended the same event.
While most of us now assume that they are back together, it appears they are keen to keep their relationship on the down-low.
Ali Hewson said she was delighted to see so many well-known faces get involved, with a number of them donating or producing art for the fundraising auction.
"I'm very excited about this, there's been a lot of goodwill for it. I was actually surprised how easy it was to get people involved, they were all very willing. There were only a few who were a bit late in, but I think they were terrified," the mum-of-four said.
Adi Roche, Chief Executive of Chernobyl Children, commended Irish celebrities for taking part.
It took five months for Adi and Ali to organise the campaign, and some 300 pieces of art were donated.
Funds raised from the auction will go toward the charity's medical initiatives to help children in Belarus and Ukraine.
Supermodel Helena Christensen, REM's Michael Stipe, actor Patrick Bergin, Saoirse Ronan, Colin Farrell, Neil Jordan, Lottie Ryan and Ryan Tubridy were among the top names to contribute.
Other guests at last night's function included model Roz Purcell, Norma Smurfit, Brian Purcell, Roz Lipsett and Karen Koster.
