We spotted Gwen Stefani wearing a revealing black sequined jumpsuit to the afterparty for "Tree of Life" in Cannes yesterday.

All week the pop star has been photographed frolicking around the French Riviera with her family. Must be nice to be rich and famous, right?

But Gwen is more than just a pretty face.  In March she made a $1 million donation to aid the Japanese earthquake and tsunami relief effort.
