Their music has inspired fans all over the world — and now Britney Spears, Justin Bieber, and Lady Gaga are using their fame to help soothe the pain of one family’s tragedy.

The multiplatinum trio have joined the Show Your Hearts campaign, a charity drive to support three children who were involved in a July 3 car accident that claimed the lives of their parents and left two of the siblings paralyzed.

The stars have taken to Facebook and Twitter to urge fans to join the cause — either by simply changing their profile pictures, or by donating via text message or credit card. In one recent tweet, Bieber expressed his appreciation by saying, “Seeing u all come together for #showyourhearts is pretty amazing. Keep donating and spreading the word. Super grateful and proud of my fans.”

The plight of the Berry family — including paralyzed brothers Peter, 9; Aaron, 8; and injured sister Willa, 6 — has drawn the attention of a number of celebrities, including Kim Kardashian, Mike Tyson, Chad Ochocinco, the Miami Heat, Maroon 5, and Katy Perry.
