We hope you wore your sexy panties instead of your granny panties today, because it's National Underwear Day! In honor of this special day (why it's not a national holiday is beyond us), Lydia Hearst is hosting the Sixth-Annual National Underwear Day celebration at Espace tonight. We'll be there, obviously. Since we can't take all of you with us and don't want to deprive you of all the near-naked eye candy we'll be ogling, we thought we'd share a photo of one of the models walking in the show. This is Christopher Fawcett, and he'll model undies by DKNY and 2(x)ist in tonight's presentation. We dare say he has a Jesse Metcalfe element about him — like he just trimmed Eva Longoria's hedges on Desperate Housewives. Though his pose here looks more than uncomfortable, it sure does highlight, uh, his fabulous abs. But, you know, now that we're looking closely, we're not so sure he's even wearing underwear in this picture. We guess we'll just blast Sisqó's "Thong Song" while we find out. —Sharon Clott
