Kaia Gerber flashes a bra top under her jacket while on a hike in Los Angeles with her new beau Austin Butler and his small white dog

Kaia Gerber and Austin Butler headed to West Hollywood’s Tree People Park together on Monday. The 20-year-old Vogue model was spotted with the 30-year-old actor’s small white dog as they walked side by side. The budding lovebirds were both wearing blue and she had on a pair of black, Daddy-O II Ray-Ban sunglasses as they got their daily steps in.

Kaia flaunted her model frame in a pair of figure accentuating leggings from Gymshark.

She wore them with a tiny blue bra that she covered with a shrunken navy blue jacket.

Cindy Crawford’s look alike daughter left the outerwear unbuttoned, exposing a bit of her flat stomach.

She left her brunette hair loose, leaving the short cut to fall gently at her shoulders.

Austin complemented the Calvin Klein model’s casual look with a distinctive outfit of his own.

He was dressed in a cutoff graphic t-shirt with a white shirt layered underneath.

The ex of Vanessa Hudgens teamed his top with a pair of blue sweatpants and a pair of black sneakers.

Butler’s dirty blonde crop of hair was gently disheveled as he led the way, guiding his small pup on a leash.

The duo has been romantically linked since December, a month after the American Horror Story actress’ split from boyfriend Jacob Elordi.

A source told People that the model ‘seems really happy’ with her new romance with Butler and ‘all of her friends think he’s really cute.’
