This afternoon, the Daily Transom rang up Peter Davis, Tinsley Mortimer's brother-in-law, to inquire about Ms. Mortimer's upcoming role on Gossip Girl. It turns out that unlike Lydia Hearst, who played a character in the show, Tinsley's role is a cameo!

So What's Tinsley's role on the show?

She's playing herself. I think it's sort of tongue-in-cheek. Tinsley lives the life these kids portray on the show only they're much younger of course.

Where was it shot?

It was at a soundstage in Brooklyn, not the Hamptons.

What was the context of the scene?

She said it was a sort of party scene, some kind of party where everyone is in all white.  read more »

The Observer's version of March Madness entered a new phase at midnight last night when votes were tabulated for the Final Four face-off in our Socialite Slapdown contest.

The contest—which gained a bit of heat last week when Page Six reported on socialites' efforts to stack the votes in their favor—closes with four finalists: Publishing heiress, model and bag-designer Lydia Hearst faces off against socialite/style writer Derek Blasberg, and Lauren Davis, socialite and Vogue editor, faces off against Peter Davis, the mocialite-loving ... style writer!  read more »

Who can claim the title of 2007’s most socially social New York society clan? In a major year-end party wrap cobbled together by Style.com, the aesthetically-inclined Web site asks—and, thank gawd, answers—that very question.

On one side of the party divide is the Peter and Minnie Davis/Tinsley Mortimer team. (Mr. and Ms. Davis are, for those who didn’t know, Ms. Mortimer’s siblings-in-law.) On the other: Ann Dexter-Jones and her three party-hardy kids—Samantha, Mark and Charlotte.

As Style points out, it’s been quite a year for both clans: Topper and Ms. Mortimer’s wedding got a major write-up in the Times; and Ms. Davis tied the knot with Syriana director Stephen Gaghan. (What they don’t mention, however, is that 2007 was also the year society scribe Mr. Davis found true love in a certain young social, Paul Johnson-Calderon.)

Meanwhile, Mr. Ronson’s single, Stop Me, climbed to the number-two spot on the British charts—no small feat, to be sure. What’s more, Samantha Ronson was, for a while anyway, queen of the tabloids, soaking up the buzz as her friendship with Lindsay Lohan continued to heat up. And then there’s their younger sis Charlotte, who we caught up with not long ago at her Nolita boutique, where she was introducing her 2007 Resort collection. Ms. Dexter-Jones, too, told us all about her new lease on life post-divorce, loving the high-thread-count sheets at her new digs in the Bowery Hotel.

In the end, though, there can only be one winner; (as Heidi Klum might say, “You’re either in or you’re out.”) And in this case, Patrick McMullan must pick the winning bunch—“that ultimate litmus test of social visibility.” While the Dexter-Jones/Ronson squad racked up an impressive 422 photos credits on the social shutterbug’s Web site, the Davis/Mortimer clan reigns supreme. The trendy trio said "cheese" for Mr. McMullan’s lens a whopping 732 times.
