Every day more and more celebrities are working to raise money for the victims of last Tuesday's devastating earthquake in Haiti. [article id="1629973"]CNN hosted a telethon[/article] earlier this week, and George Clooney, Wyclef Jean and MTV have joined forces with a number of entertainers for Friday's [article id="1630013"]"Hope for Haiti Now: A Global Benefit for Earthquake Relief."[/article] Now, Adam Lambert, Scarlett Johansson and Nick Jonas are also encouraging fans to donate to relief efforts.

Lambert appeared on "Entertainment Tonight" on Wednesday, urging viewers to give to the Red Cross. "The people of Haiti need your help," he said. "The images are heartbreaking, the loss of life devastating, but tonight you can help. ... Do something that will change a life, do something that will make a difference. Don't just let the images on television fade to black. Reach out and help Haiti today, tomorrow and every day until they are out from under the rubble. Your donations will make a difference. Your generosity, no matter how small, can help pull them out of this horror."

Scarlett Johansson, who is currently appearing on Broadway in Arthur Miller's "A View From the Bridge," is working with Oxfam to auction off four tickets to the opening night of her play and a chance to meet the actress after the curtain call this Sunday (the same night [article id="1629858"]Lady Gaga is donating proceeds[/article] from her tour to charity for Haiti). As of press time, the winning bid on the eBay auction stood at $2,225.

When MTV News spoke to [article id="1630120"]Nick Jonas[/article] on Wednesday, he revealed that he was "working some things out right now" to be a part of the Haiti relief effort.

"Because it's not confirmed, I can't necessarily share it just yet," Jonas said on the phone from his Administration tour. "I think that the main thing to remember is we can all do something whether it's a little bit or a lot. I'm willing and ready to help if I can in any way. I definitely feel for the people in Haiti."

And like [article id="1629884"]his brother, Joe[/article], Nick would like to visit the suffering country. "If an opportunity does come up for us to be able to go visit, I think that would be an amazing trip," he said. "But I think it's about taking it one step at a time and trying to do what we can here first."
