Who doesnt love an A-list actor or buzzy singer making an unexpected cameo?

His clothes and shows are always a beautiful expression of his work and virtuosity, so it felt exciting.

Its yellow, elegant, fun, and made for meso I loved it, says Ross.

I felt like a slinky, foxy, burst of sunshine in it.

Rosss fabulous moment on the Marni catwalk came about entirely organically, says the star.

Ross and Risso immediately began brainstorming their approach for her runway walkand they landed on crafting a theatricalmomenttogether.

As for what other preparations went into her splashy fashion week moment?

A lot of stretching, and sleeping, because the time difference is brutal.

Of course, this wasnt Rosss first rodeo taking on a high-fashion runway.

Back in the 1990s, Ross famously walked thespring 1991 Mugler showwith her mother, Diana Ross.

(An iconic mother-daughter moment, if you ask us.)

I dont think Ive walked for a designer since then, says Ross.

It completely brings me back to my first love.

I love the process: The fittings, all of the amazing artists, and the clothesalways the clothes.

It was fun to rediscover my model legs.

Her favorite, she quips, is whichever one lets me keep the clothes!
