Hailey Bieber flashes her toned tummy in a mesh top and a pair of string bikini bottoms on Instagram

She has been trekking across the country this week with husband Justin Bieber, 26, in their luxurious RV worth a startling $1million. 

But Hailey Bieber may have been missing Los Angeles on Sunday as she shared a stunning bathing suit picture taken in the backyard of her and Justin’s home to her Instagram Story.

The 23-year-old face of Bare Minerals flaunted her enviable physique in a mesh top and a pair of string bikini bottoms designed by fellow model Emily Ratajkowski.

‘ily @emrata @inamoratawoman,’ captioned Hailey on her sultry self-portrait.

Aside from her killer body, Bieber also showed off her enviably clear complexion and styled her golden tresses into a sleek bun.

She also recently revealed that she is ‘trying to transition over to eating mostly plant based’ and encouraged her followers to send her suggestions for plant based related films and books.

Hailey and her hubby Justin recently paid a visit to pal Kanye West’s ranch in Wyoming, amid the 43-year-old rapper’s mental health struggles and martial issues with wife Kim Kardashian, 39.

In a series of clips shared to Instagram by one of West’s associates on Saturday, the 26-year-old pop star and his model wife can be seen pulling up to the ranch in their luxury RV. 

But on Sunday, Justin spent some one-on-one time with his wife of nearly two-years, while enjoying a romantic picnic in the grass.

‘Lil picnic wif bae,’ wrote Justin in his post’s caption.

In a sweet snapshot shared to his Instagram, Justin posed shirtless with Hailey in his arms, while a picnic basket and a meat and cheese platter rested next to them.

Hailey – donning a pair of gold hoop earrings and a black tank top – had her arm stretched out in front of her as she took the pair’s loved up selfie.

Justin had his hand in Hailey’s shirt, while her hand rested delicately on top of his. 

After posting his photo with Hailey, the Baby singer spammed his 142million followers with back-to-back selfies.

In one of the shots, Justin can be seen tying the laces of his sneaker on a bench located near a picturesque lake.

In the second shot, Bieber can be seen squinting his eyes as he posed facing the sun. 

Justin Bieber’s stop in Wyoming on Friday is just one of many the Grammy Award-winning singer has taken on his impromptu road trip with Hailey.

He has been generously sharing snapshots from the nature driven trip on his Instagram.

On Friday, Bieber uploaded two portraits of himself and Hailey posing with their arms around one another as they took in the breathtaking views.
