According to TV Line’s sources, both actresses have been invited back on a guest star basis, but will anyone miss them? Szhor will likely have the most incentive to reprise her role on the show, which seems to serve in large part as a vehicle for its female stars to land fashion endorsements. In addition to the lack of screentime this season Momsen has been dropped as the face of Madonna’s Material Girl clothing line, dropped from IMG’s roster and had a brief moment as the face of a Galliano perfume, but LVMH has been dropping everything Galliano like it’s hot so safe to say the fashion “it” girl ship has sailed there. At least she has that angsty rocker thing to fall back on.

Szhor, who’s been popping up at more and more fashion events (including the MET Costume Institute Gala in the sparkly pipe cleaner look above that barely escaped our list of WTF? moments), has been taking full advantage of the endorsement opportunities for a while now though, so  we’re pretty sure she’ll be more ambitious about continuing on as part of the cast in some way.

Momsen has been trying to up her rebel image with a panda-eyed beauty regimen, stripper heels and shock statements, Fanning (who goes by Dakota F on the IMG site) has shocked everyone by demonstrating that child stars can pull off the role of well-adjusted young adult.

Not that the teen angst thing didn’t work for a while – in addition to landing the Material Girl campaign, John Galliano chose the teen rocker to endorse his Parlez-Moi d’Amour fragrance. {Styleite} Being honest, too much black eyeliner and lingerie is an almost perfect representation off Galliano’s enfant terrible line. Even if your natural reaction to Momsen is that “she’ll grow out of it in 5 years,” there are certain segments of fashion where her rebellious reinvention is a natural fit.

With this year’s clothing moving towards a more feminine, less edgy aesthetic, maybe there just weren’t enough segments for IMG to make this particular Gossip Girl work.
