It’s no secret that Gossip Girl cast members Blake Lively and Leighton Meester have proved themselves to be stylish on set and off. Now it seems that both ladies will be fronting major fashion campaigns next year. Lively is the new face of Chanel, while Meester is rumored to be Missoni's new model, according to Elle UK. Meester, who currently appears in campaigns for Vera Wang fragrances and Herbal Essences, will be modeling for Missoni in a campaign launching in summer 2011.

Taylor Momsen has been making fashion headlines for a few seasons now thanks to the Gossip Girl's controversial style. (Think: no pants.) But it seems bona fide fashion heavyweights are looking to the teen spirit for inspiration, too. Not only has Momsen found herself in the good graces of Madonna, she's also apparently piqued the fancy of John Galliano. "Momsen was hand-picked by Madonna to be the face and muse of Material Girl, the juniors label that will launch at 200 Macy’s stores next week," says Women's Wear Daily. The line was in large part designed and inspired by Madonna's own spawn, Lourdes, but it's Momsen that will act as its spokesperson. "The role entails doing the launch of the line on Aug. 3 at Herald Square. And I’ll be tweeting and talking about the line. We did a photo shoot for the first pieces of the collection. It’s a really great line. It’s really cool," Momsen told WWD.

According to a little bird that spoke to Nylon, Gossip Girl's Taylor Momsen is "shooting a campaign for a very big fashion brand today." And, the international brand that the actress and musician is playing muse to is none other than London's New Look. The choice isn't all that surprising given the brand has a thing for punk loving 'it' girls-cum-mannequins like Pixie Geldof, who designed a line and modeled it for the retailer back in 2008.

Rumor has it Blake Lively -- the Gossip Girl star and former Vogue cover girl -- is extending her reach with regard to the fashion industry. Specifically, she may soon be playing muse to none other than Victoria Beckham. Whether it's the hair (which the New York Times claims is the new "Rachel") or maybe her unique style (she doesn't have a stylist and still has managed to land quite a bit of praise for her wardrobe choices), there's no doubt Lively's sartorial star is rising. As recently as October, Lively was seen sporting a VB design for SS10 on the red carpet; and, now, apparently Mrs. Beckham herself has taken notice.

Tonight on Gossip Girl, three turns out to be the loneliest number when the OM3 between Dan, Vanessa, and Lizzie McGuire turns out to be more complicated than their private parts originally expected. But let’s be honest -- we’ll go for the threesome, but we’re staying for the Gaga. On tonight’s episode, Leighton Meester’s Blair Waldorf continues in vain to impress her NYU classmates, this time by promising them a private Lady Gaga concert. The details of her guest appearance are cloudy at best: she wears a red gown with a 30-foot train. She performs her new single “Bad Romance.” She tells People, “It’s very performance art.”

Gossip Girl is a watchable program if you abandon the following luxuries: convincing actors, character development, plot construction, conflict resolution, and expectations of how children age 16-20 act in the real world. In fact, toss aside all those expectations and Gossip Girl is like The Wire: A gritty, true-to-life portrayal of a corrupt, sleazy city. A city where palms can be greased with hundred dollar bills and lives can be changed with the snap of well-manicured fingers. Where Polish maids can hold better tales than any of the pretty young things. Still, some of us are on a time-delay when it comes to GG and like the experience of watching the soap unsullied. So having the show's most critical reveal spoiled in a poorly written headline as we peruse the day's gossip is frustrating. Thanks a lot Tim Stack at Entertainment Weekly! Spoilers ahead, if you hadn't picked up on that yet.

Are threesomes the final taboo of network television? The CW sure seems to think so. Yesterday, The Wrap obtained a strongly worded letter from the Parents Television Council, who got all riled up over an upcoming episode of Gossip Girl in which three of the show's characters engage in an OM3. The PTC writes, “Television is profoundly influential in the lives of children, especially when it comes to sexual decision making -- it has even been described by one researcher as a 'sexual super-peer' -- signifying television's power to amplify, many times over, the peer-pressure teens are already feeling to engage in high-risk sexual behaviors." Maybe they're on to something.
