Lady in leather! Susan Sarandon looks sexy at 70 as she flashes her cleavage in black and white outfit at horse races

At 70 years old, Susan Sarandon still enjoys showing off a bit of cleavage.

And the Academy Award winner looked fabulous on Saturday when she flashed the flesh at the Santa Anita Park in Arcadia, California.

She strode the lavender carpet at the 2016 Breeders' World Championships, which was on its second and last day.

The Thelma & Louise star had popped on a pair of black sunglasses with orange rims that artfully complemented her cropped, curly red hair.

What looked like a silver medallion dangled between the large collar of her white blouse, which she'd tucked into a pair of black slacks.

She rounded out her ensemble with a pair of faded black and pine green leather boots that elongated the look of her toned legs.

A few other famous names had turned up as well, including Elizabeth Banks, whose splashy throwback outfit featured a netted veil and headgear resembling berries.

Images from a landscape painting of a garden, complete with bridges, were splashed across her otherwise white pleated skirt. 

Susan and Elizabeth looked like they were having a great time as they caught up inside the star-studded event.

Meanwhile, Emily Ratajkowski wore a figure-hugging white miniskirt that showcased her vertiginous legs as she teetered across the carpet in nude stilettos. 

Susan recently became a grandmother again when her daughter Eva Amurri gave birth to son Major James Martino last month. 

She is also grandma to Eva and husband Kyle Martino's two-year-old daughter Marlowe.
