Adam Lambert, John Legend Sing G-Star's Praises During Fashion Week

'It is high-fashion, but it's also their vision and their brand,' says celeb spokesmodel Liv Tyler.

NEW YORK — It's New York Fashion Week, and that means the models are primped, the celebrities are front row and the designers are putting the finishing touches on their designs. And, on Tuesday night, the fashionistas flocked to Hammerstein Ballroom to check out the latest collection from denim brand G-Star.

Adam Lambert, Estelle and John Legend sat front row alongside the company's latest celebrity spokesmodel, Liv Tyler, to see the models strutting down the catwalk in funky jeans and brightly colored frocks.

"I've been pretty excited and lucky," Tyler told MTV News about her role as the company's face. "I'm enjoying it a lot, because it's something I've never really done before. I like the brand as a whole. I really like what they're doing. It's sort of fashiony, but it's not. ... It is high-fashion, but it's also their vision and their brand. It's authentically them."

Tyler isn't the only fan of the company; Kelly Osbourne also made her way to the show. "They're my favorite denim line, to be honest, because I love the cuts, and they always push the boundaries a bit," she said. "Their textiles are amazing. When you get up close, there's always something about it that's a little quirky."

Fellow Brit Estelle raved about the fit of the brand's signature jeans. "The jeans fit! Black-girl booty, and the jeans fit!" she laughed. "The structure is great, but the brand is definitely a go-to. Nothing is rubbish."

Mena Suvari said the G-Star show is a regular stop on her Fashion Week schedule. "When I'm here in New York for Fashion Week, I like to support my friends, and I've been coming to G-Star for a few years now, and they are so wonderful to us," she said. "And to me, it's denim couture. It's just awesome to see. It's really different and sexy and interesting. Their denim rocks, and it's comfortable and unique. It's special, and they always have the best shows."

"American Idol" runner-up Adam Lambert heard about the show through the grapevine. "I was just told this is the place to be," Lambert said. "So I thought, 'All right, I'll put on my duds and be here.' "

Legend decided to check out the show this year after he had become a fan of the company's clothes. "I thought it would be fun. I like what they do," he said. "I think they got a cool brand and cool energy around their brand."

"One Tree Hill" star Robert Buckley said that even if you don't like the clothes, the show is just too awe-inspiring to miss. "G-Star's the one company — they don't put on a fashion show, it's more like a fashion spectacular ever year," he said. "It's like Cirque du Soleil-meets-high fashion, and so I'm honestly excited to see what they pull out of the hat this year."
