Some early-arriving Summit attendees were buzzing about the A-listers around the Stein Eriksen Lodge. "Curb Your Enthusiasm's" Larry David was apparently walking the halls, as was Gwen Stefani and husband Gavin Rossdale.

Julia Louis-Dreyfus, who's made cameos on "Curb," was also around. And on Sunday, "Heidi" and "Spencer" of MTV's faux reality series "The Hills" were spotted having lunch at the lodge.

Celebs were participating in an annual Deer Valley skiing event to raise money for charity (it will air on CBS Dec. 21).

But perhaps the most intriguing celeb sighting came during Mediapost's Search Insider Summit -- an event before the email conference -- when former "Beverly Hills, 90210" star Ian Ziering approached the registration booth.

Was he interested in the latest SEO tactics? Not as much as his friend from L.A. who works in online marketing and wanted some info.
