Fashion Week Photos: Musicians Spotted Backstage & Front Row
Kelly Osbourne and Lourdes Ciccone-Leon (a.k.a. Madonna's daughter) attend the Zac Posen Spring 2013 fashion show during Mercedes-Benz Fashion Week on Sept. 9, 2012.

The children of rock and pop royalty -- Kelly Osbourne and Madonna's daughter Lourdes -- showed off their style at Zac Posen's NYFW show.

As the weekend came to a close, New York Fashion Week continued the trend of dramatic, futuristic collections that had defined runways for the first few days. However on Sunday (Sept. 9), there were also spring styles that looked back in time. Read on to see where stars like Gavin DeGraw, Paula Abdul and A$AP Rocky spent their day during the spring 2013 NYFW.

Timo Weiland

Rap beats filled the tents at New York's Lincoln Center during Timo Weiland's spring show, and yellow and peach pastels filled the space as geometric patterns and billowing gowns added to the runway mix. A hip-hop influence ran rampant throughout the collection in the form of relaxed silhouettes and color-blocked shorts.

A dapper Gavin DeGraw looked on from the front row in casual, cool look: a denim jacket over his black T-shirt, dark jeans, grey suede oxfords, Ray Ban sunglasses and a dark blue fedora. DeGraw has a unique '80s hip-hop style that many seem to over look. The tattooed model from Lady Gaga's "Born This Way" video, "Zombie Boy," was also sitting in the front row in a simple black ensemble.

Emerson

Inspired by the madness and horror of '70s films like "Amityville Horror" and "Carrie," Emerson's collection revealed a dark and sinister spring to come. Designer Jackie Fraser-Swan crafted cobweb-like netted shirts, jagged asymmetrical lines and black leather creations. Spatters of red popped throughout the sophisticated collection, accentuating the feminine, billowing pieces that nodded to the high school setting in Stephen King's "Carrie."

Looking onto this terror-induced spring collection was former "X Factor" and "Idol" judge Paula Abdul, who was stunning in a loose red Emerson jumper, accentuated with a black clutch and gold cuff. Abdul's makeup was minimalistic, with just a sweep of bronze across her eyes. Carah Faye from Shiny Toy Guns, electronica duo Icona Pop, Natalie and Elliott Bergman from Wild Belle, and singer-songwriter Natalia Kills were also in the audience at Emerson's show.

DKNY

As "New York" by Les Butcherettes and Notorious B.I.G.'s "Hypnotize" played at DKNY's show, models dressed in ultramodern and geometric pieces strutted down the catwalk. Donna Karan's deep appreciation for New York City was clear this season, with a collection that featured leather-trimmed skirts, cotton blazers and bold racerback gowns. U.K. soul singer Lianne La Havas attended the spring show in a DKNY black jumper, sliver choker and orange geometric print clutch.

Y-3

Jiro Amimoto was spinning songs like Kamera's "Love Is What We Need" as models sauntered through a dark warehouse at the Y-3 show Sunday (Sept. 9). The bubbling ambient sound perfectly spoke to the futuristic, sporty collection. Signature tracksuits were given an ultramodern twist as dresses took on voluminous silhouette. The 3D theme started by the dresses made its way into the runway décor as 3D projections by artist Devan Harlan played onto the studio walls.

Natasha Bedingfield sat front row, looking much softer than she did at Saturday's Christian Siriano show in a sheer, flowing white blouse, dark jeans, black pumps and a thick wraparound gold necklace. Her makeup was simple: just a dark eye and a pink lip. Rapper A$AP Rocky was also in the audience at the Y-3 show, and seemed to be in hiding with his hoodie pulled almost completely over his head. Other notable attendees included David Beckham, Lupe Fiasco and Isabel Lucas.

Catherine Malandrino's Black Label

Melodies by Summer Camp, Get Well Soon and Francis Lai trumpeted into the studio space at Catherine Malandrino's spring 2013 show as her romantic, French-inspired collection was revealed. Delicate modern pastel dresses and majestic silhouettes took form in white stretch leather, French cotton guipure lace and Victorian-style blouses. Malandrino clothes defined confident femininity. Producer Rico Love stopped by the catwalk, showing off his Parisian style in a pale blue floral shirt under a tan blazer, with red pants and matching sunglasses.

Zac Posen

From the opening riffs of Glenn Miller's "Moonlight Serenade" to the soothing sounds of Etta James' "Sunday Kind of Love," it was clear that Zac Posen had stitched together a glittering, retro look for Spring 2013. Romantic and playful, the Grace Kelly-inspired collection's palette consisted of navy, burnt sienna and light sea green colors. Patchwork floral dresses and timeless gowns spoke to the simple elegance and raw glamour of the '40s.

Kelly Osbourne watched from the front row, rocking her own version of glamourous in a minimalistic cream Posen dress and her signature pale purple hair. Madonna's daughter Lourdes Ciccone-Leon also attended the show in a laid-back, rocker chic look, following in her mother's footsteps by taking a strong stance in the fashion community. The young Material Girl designer wore a sheer black shirt, torn jeans and extended cat eye shades.
