Now that heriess/socialite (so many of them these days) Lydia Hearst has had her debut role on Gossip Girl, tumblrers are wondering which Manhattan media celebs could possibly turn up on the show next. Oh that's kind of fun! Let's see, you'd have to have dating columnist Julia Allison, of course. Socialite Leven Rambin, for sure. (Plus, she's already an "actress"). Men's Vogue writer and man-about-town Hud Morgan could turn up somewhere, along with a few other notable friends/foes of this here blog. Read our seven casting ideas, after the jump.

Julia Allison
 The aggressively self-promoting and increasingly famous dating blogger/life-liver could turn up as Rachel Alice, a pesky gossip writer from a trashy tab newspaper who wants to do a story on Lily and Bart Bass, but quickly discovers that the real story is, of course, the kids. Using her youthful looks to her advantage, she infiltrates to write a nasty story, seducing Chuck at the same time. Eventually, in a dramatic waterside scene, she is exposed and an angry Blair pushes her into the East River. 3 episodes

Leven Rambin
 The soap actress, who has guested on Lipstick Jungle in the past, could play Lux Rivington, the queen bee of a rival school who must ally with Blair to fight a proposed merger of their two schools. She and Lux grow increasingly close until Lux tries to kiss her and Blair runs away. Highly embarrassed and never wanting to see Blair again, Lux grudgingly seduces a wealthy alum of her school who donates a ton more money, making the possible merger moot. 5 episodes

Hud Morgan
 Hud, the fruitini-drinking master of slap fights, could guest as Chad Stanley, a surprisingly straight fashion writer who goes to interview Blair's mother Eleanor about her fashion line. He is probing and cruel when interviewing Eleanor. She is angry and defensive at first, then turned on. The two try to "be intimate" but Chad is unable to perform, leaving Eleanor with leverage to demand his article be written as an adoring puff piece. 1 episode

Kristian Laliberte
 The gay PR queen could play Timmi Devereux, a gay Upper East Side guru who takes the recently outed Erik van der Woodsen by the, ahem, ears and shows him the scene. All-gay tea parties, drinks at the hippest Hell's Kitchen spots, and a Broadway opening night gala. At the party, Erik meets a young dancer played by Broadway hottie Nick Adams. They hit it off instantly, and Timmi, who's been harboring a crush on Erik, gets a little sad. But, in the end, he decides to let them go and trots off into the night. 2 episodes

Arden Wohl
 Crazy "bohemian" socialite Arden could play Avia Wuhrer, an up-and-coming video artist whose parents own a gorgeous flat in a sketchy part of Bushwick (think upscale McKibbin). She meets Vanessa at a video show, and instantly has an eye for Dan. Dan is conflicted, as he has been dating Vanessa but finds Avia mysterious and sexy. Avia gets Dan drunk and they almost kiss on the L train platform, but suddenly Avia stumbles and gets hit by an oncoming train. Everyone learns a lesson about death and Dan returns sheepishly to Vanessa. 4 episodes

Emily Brill
 The daughter of former media tycoon Steven Brill, Emily could play Kitty Bowdoin, a formerly chubby classmate of Blair and Serena's who returns to Constance Billard, having shed many pounds at a special school, ready for social stardom. Blair, of course, will have none of it and sets out on a campaign to get Kitty big again. We don't so much mind because Kitty is a manipulative harpy. Evil, food-centered machinations ensue and Blair wins when Kitty's dress bursts at a huge social event. Whiffs of Mean Girls abound, sure, but it's only for 2 episodes

Oh a blog can dream, can't we? Who else might be fun to see on the show? Who would they play?
