Celebrity signatures have never been more valuable.

Beginning today, E! will kick off its Autographs to Help Haiti online auction to support the ongoing relief operations in Haiti and to aid those displaced by the recent disaster in Chile.

You can bid on beautifully framed Plexiglass panels signed by celebrities such as Sandra Bullock, Mariah Carey, Tina Fey and Justin Timberlake and tons more of your favorites—while knowing you're helping victims of the tragedy in Haiti.

Also, be sure to check back after the Oscars for framed photos of celebs that will be auctioned off to assist relief efforts in earthquake-stricken Chile.

At the end of the auction (you've only got until March 11!), all proceeds from the winning bids will be donated to the Red Cross.

Hurry and click here to bid!
