And the Big Reveal of Will and Kate's Trip...

Did you just feel yourself getting a little less glamorous, California? That's probably because Prince William and wife Kate wrapped up their three-day tour yesterday, heading home via (gasp!) a commercial flight on British Airways, Radar reports. More details from their trip:

• The biggest, or at least most amusing, reveal of the trip: Kate is allergic to horses. But apparently she'll do anything for love, as she got up close and personal with the equines at Wills' Santa Barbara polo match and is trying to overcome her allergy. People reports that she told the Polo Club president's wife, "The more time one spends with [horses] the less allergic you become."

• Another, er, big reveal? Kate is really, really skinny. E! is concerned, but was reassured by a royals insider who explains, "I don't think we have a problem like Di did with weight," but that Kate simply lost weight for her wedding and then "carried that over to her first official tour."
• Of course, the royal pair spent time mingling with celebrities, and not just at the BAFTA gala. Check out pictures of them with Reese Witherspoon in the gallery.
