Lady Gaga, Kim Kardashian, Justin Bieber Show Their Hearts For Orphaned Victims of Car Crash

Justin Bieber, Lady Gaga, Britney Spears and Khloe Kardashian are just a few of the celebrities that are using their enormous social media influences to a great cause--the “Show Your Hearts” campaign.

On July 3, the unimaginable happened to family of five in Houston, Texas. When they were on their way home from a Fourth of July weekend vacation, another car veered into their lane and hit the family's minivan head on. The parents, Joshua and Robin Berry, were killed instantly. Their two young sons, Peter, 9, and Aaron, 8, were paralyzed and remain in hospital for their spinal injuries. Meanwhile, their daughter, Willa, 6, suffered broken bones.

The “Show Your Hearts” fundraising campaign to benefit the Joshua and Robin Berry Children’s Trust officially began yesterday, July 27, and many celebrities--including the Kardashians, Diddy, Jennifer Hudson, Selena Gomez, Julianne Hough, Nicole Scherzinger and “Glee” cast members--are doing their part to help the Berry children.

Lady Gaga tweeted to her more-than 12 million little monsters yesterday afternoon, tweeting, "Monsters: There are orphans that need our help. A tragic story that left them paralyzed www.showyourhearts.org or text BERRY to 85944."

Teen dream Justin Bieber followed suit, tweeting to his 11 million followers, "Spread the word and trend #SHOWYOURHEARTS and when u make a donation post the new profile pic 2 show the world! LEGGO!"

Bieber has also dedicated his Twitter page to the Berry children, urging his fans and other celebrities to trend the official hashtag #showyourhearts. The teen singer recently posted his official video for his original song, "Pray," on his Twitter page, dedicating it to the Berry children.

On Wednesday, reality star Khloe Kardashian also tweeted, "This truly breaks my heart!!! http://t.co/hmYH1qf Please show these children your support!!!!!! Show Your Heart <3"

Daytime television personality, Ellen DeGeneres, on her television show's home page, asked fans to "join me in raising awareness and sending love and support to this family."

These stars and others are asking people to spread awareness about the orphaned Berry children by swapping out profile pictures and avatars for the custom “Show Your Hearts” artwork.
