Kate Hudson, Ashley Benson and Demi Lovato lead stars at Stella McCartney x ... trends now

Kate Hudson, Ashley Benson and Demi Lovato led a cavalcade of celebrities who turned out for the Los Angeles launch party of the latest Stella McCartney x Adidas collaboration.

Ashley, 33, who shot to fame on the smash hit series Pretty Little Liars, unleashed her animal instinct in a gold and black tiger print suit for her latest public appearance.

She went topless under her blazer, serving up a generous helping of cleavage and offering a view of her enviably taut midriff as she posed up for the shutterbugs.

Meanwhile Kate wore a fashionably oversized and rumpled baby blue jacket with a matching miniskirt and a shimmering silver bra-lette dripping with fringe.

The Almost Famous actress, who is the daughter of movie star Goldie Hawn and musician Bill Hudson, balanced expertly on a sleek white pair of heels.

Demi, who declared herself 'nonbinary' and expressed a preference for 'they/them' pronouns but later announced she will also accept 'she/her,' made a splash in a sleek black cocktail dress.

She wrapped a camel-toned cutoff bomber jacket over the look, accessorizing with a sleek black leather handbag and slipping into a strappy pair of stilettos.

The fete was awash with people who were born into show business, including Bruce Willis and Demi Moore's younger two daughters Scout and Tallulah Willis as well as Michael Jackson's daughter Paris.

Stella herself, the daughter of Beatles legend Paul McCartney and his late first wife Linda, exuded a retro chic elegance in a boyfriend fit coat-dress on her brand's big night. 

Mick Jagger and Jerry Hall's daughter Georgia May Jagger glowed in a 1960s style bias cut cocktail dress, while Miley Cyrus' sister Noah slid into a white look reminiscent of Little Bo Peep.

Kate and Stella could be spotted posing up a storm for the shutterbugs alongside a flesh-flashing Madelyn Cline, star of Netflix' buzzy series Outer Banks. 

Paul's fellow rock stars also made their presence felt at his daughter's knees-up, including Kim Gordon formerly of Sonic Youth and Krist Novoselic of Nirvana fame.

Versatile singer-songwriter Brandi Carlile rocked a powder blue suit during the evening's festivities, which she attended on the arm of her wife of over a decade Catherine Shepherd.
