NewsCenter 5's Jorge Quiroga reported that the "Tonight Show" host and Andover, Mass., native Jay Leno is auctioning off a Harley-Davidson motorcycle on eBay and sending the proceeds to the Red Cross.

The motorcycle will by signed by Leno and guests on his show.

"Miss Congeniality" star Sandra Bullock is living up to that title and more. Bullock donated $1 million to the Red Cross to boost its Southeast Asia Relief Fund.

It is Bullock's second million-dollar donation. Her first came following the Sept. 11, 2001, terrorist attacks.

Leonardo DiCaprio has also reportedly opened his wallet to give a large donation to UNICEF. He's also set up a link on his official Web site for others to donate.

A Thai island where DiCaprio shot the 2000 thriller "The Beach" sustained massive damage from a tsunami.

Movie stars are not the only ones pitching in. Other entertainers are donating their time.

Irish rockers U2 and other groups like Coldplay and Franz Ferdinand will take to the stage to help raise millions of dollars for tsunami victims during a Live Aid-style concert.

Organizers are hoping to hold the event on Jan. 22 in Wales.

British pop star Boy George is adding his voice to the humanitarian efforts. He'll collaborate with Olivia Newton-John and Robin and Barry Gibb of the Bee Gees on a new charity single. The ballad, titled "Grief Never Grows Old," will hit stores later this month.
