A host of celebrity pals stepped out to support designer Stella McCartney on June 10 as she unveiled her Spring 2014 collection.

Superstar Madonna was spotted giving friend Stella a big hug as she arrived at the presentation, held at West 10th Street in New York City. The 54-year-old had shunned the spring theme, opting for a black trench coat and black sunglasses. 

The singer was joined by Hollywood ladies Cameron Diaz and Naomi Watts. Cameron, 40, looked fitting for the season, showing off her model-esque frame in a white dress with matching sandals. Her hair was pinned back in a chic, tousled updo.

Stella later shared an Instagram shot of her posing with Cameron, captioning the snap, "Gals on a night out...Brooklyn! x Stella."

Naomi, meanwhile, ramped up the glamour factor in a one-shoulder black lace jumpsuit that she paired with patent sky high stilettos and a black clutch. 

Another A-list attendee was Kate Bosworth. Dressed in a pink satin frock very similar in style to host Stella, Kate posed alongside the designer. The ladies looked almost identical as they smiled for the cameras together, with their middle-parted, tousled hair.

They were joined by Danish model Helena Christensen, who wore a midnight blue and black summer dress with a black and gold studded clutch. Canadian model Jessica Stam also joined the glamourous event, wearing a strapless black number.

Paul McCartney's daughter was unveiling her latest vegan fashion collection. The presentation featured a gaggle of gorgeous models showing off Stella's new designs. 

Meanwhile, Stella has revealed plans for a new denim range to hit stores next year.

She has announced plans to focus on denim even more next year, when she will create ten different looks which will all be available in 20 shades.

"I believe it's an everyday part of everybody's life," she told WWD. "Jeans are a timeless classic with a million opportunities to inject freshness and attitude. There are a lot of eco possibilities as well with denim, which I find exciting."

The new range will be available from spring 2014.
