Alison Sweeney opened her home to a plethora of celebs, all for a good cause -- raising money for Feeding America.

On November 14th, Days of our Lives star Alison Sweeney hosted a fantastic holiday charity event -- benefiting Feeding America (an especially worthy cause this time of year) -- at her home in the L.A. area. And we've got a bevy of fantastic photos from the event for you to peruse through!

All sorts of soap stars -- including Galen Gering (Rafe, Days), Lisa Rinna (ex-Billie, Days) and Greg Vaughan (ex-Lucky, General Hospital) -- and other celebs were in attendance at the Celebri-Tree Holiday Open House, not only to help Alison celebrate the season, but also to personalize a bunch of cool Hallmark items ... a selection of which are now available in an online auction at ClothesOffOurBack.org, with all proceeds going directly to Feeding America.

And guess what? Other soap faves and stars who couldn't make Alison's actual event -- like All My Children's Cameron Mathison, Austin Peck (As The World Turns), and Gilles Marini (Brothers & Sisters, Dancing with the Stars) -- signed some items that are also available for purchase. FYI: the auction ends Tuesday, December 15th at 7PMc.

Feeding America is the nation's leading domestic hunger relief charity; more info can be found at feedingamerica.org.
