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.

Gaga is very well-known for her avoidance of pants. This past Sunday night, scores of Hollywood stars gathered at the MTV Europe Awards, and here’s a scorecard of how many celebs took a lesson from the Lady and went pants-less at some point during the event:

Katy Perry, who sported a white leotard for her performance of Firework, Eva Longoria two separate times as host of the show, Miley Cyrus while performing Who Owns My Heart, Ke$ha on the red carpet and Taylor Momsen also on the red carpet (who, whether she realized it or not, actually ripped right off Gaga with an underwear beneath a coat and boots look). Plus, Longoria also dressed as a ham at one point, though her costume was not actually made of raw meat. {The Cut}

Quite a list, no? Now you might argue that Gaga did not actually start the pants-less thing since Cher has been known to go without them and even Madonna rocked a few leotard looks in her day, but these stars never really seemed to inspire as many others to take on the look too.

With winter fast approaching, we’re not sure how popular the no pants movement will be in the mass market. As far as celebrity fashion though, Lady Gaga’s definitely setting the trends.

If you’ve been reading any fashion blog (this one included), you’ve heard about “Material Girl,” a fast-fashion juniors collection which Madonna and her daughter, Lourdes, collaborated on. The August 3rd debut at macys.com and 200 select Macyâ€s stores across the country is on track, and the retailer recently released more information on the supporting promo plans. Early bird shoppers who dress up in Madonna-wear at select stores will have a chance to win T-shirts autographed by Madonna between 10 a.m. and 12 p.m.

Additionally, the first 200 shoppers at six Macyâ€s locations will win a “Material Girl” bandeau top and $10 off “Material Girl” purchases made that day. It doesnâ€t stop there: Madonna-inspired events will be hosted at select stores on launch day including afternoon Madonna music dance parties, more exclusive giveaways and refreshments. Finally, Taylor Momsen, recently announced as the muse and face of the “Material Girl” collection, will make an appearance at Macyâ€s Herald Square between 5 and 7 p.m. for a live acoustic performance in the juniors department. Fans who spend $50 on “Material Girl” wear will have the opportunity to take a photo with Momsen.

If this doesn’t do amazingly well, you certainly can’t blame a lack of promotion. Weâ€re guessing on Tuesday the select Macyâ€s stores will be packed with teenagers who are fans of Lourdes and their moms who loved Madonna in the 80s. The cross-generation appeal actually makes the mother-daughter collaboration quite genius.

Executive Vice President of Marketing for Macyâ€s Martine Reardon said he expects the launch to create a whirlwind of enthusiasm.

“Madonna is a legendary fashion icon, and Lola has a great sense of style that reflects her global fashion view,” he said. “The national unveiling of this collection will be an incredibly exciting moment.” {Market Watch}

The apparel, shoes, handbags and jewelry for the collection will go for $12-$40. The ads featuring Momsen have popped up on the Internet, and we also caught a sneak peak at macys.com and from iVillage. Itâ€s all very 80s Madonna (faux-leather pieces and lots of lace), with hints of the plaid shirts that popped up on the Music cover. If nothing else, petite adults looking to build a convincing 80’s Madonna Halloween costume should have an easy time at it this year. And of course, weâ€ll keep you updated on the most important detail – how the collection sells!

The face of the brand has remained hush hush until now. All we knew was that a young Hollywood starlet, who lives and breathes the essence of edgy was in Madonna’s sights. The ads are finished and courtesy of Macy’s it’s confirmed that Gossip Girl star Taylor Momsen is the face of the ‘Material Girl’ ad campaign. {Stylelist} No word yet on if this means underwear and stripper heels will be involved in the line.

Even though she’s moved on to Dolce & Gabbana, we love that Madonna’s not afraid to look back on her younger style. Her daughter Lourdes, who collaborates on the collection has, over the years, may be heavily influenced by old pictures (we’re betting that’s a family photo album a lot more exciting than ours), but has honed her own unique rocker fashion sense as well. In this case, a little fashion nepotism may not be so bad.
