The model and wife of Justin Bieber delighted her 49million social media followers as she posted a series of saucy snaps showing off her figure in a backless white dress

Hailey Bieber has wowed her Instagram followers as she flashed her side-boob in a racy backless white dress.

The 26-year-old took to social media to pose in the high-necked, long-sleeved, floor-length gown.

The model completed her chic look with blue eyeshadow and a dark lipstick as she parted her hair on the side.

Hailey accessorised with diamond earrings in the shape of a martini glass and carried a light blue purse.

There were no words in the caption, with Hailey stringing together two butterfly emojis alongside a dolphin and three pink bows.

As well as showing off her side-boob, the revealing dress also displayed the tattoo on her back saying French phrase “couer d’Alene”.

Hailey’s post came shortly after the release of her interview with Kim on her YouTube series, Who’s in my Bathroom?

In the episode the pair play a game called Truth or Shot, choosing between answering a racy question or taking a shot of tequila.

One of the questions led to both Hailey and Kim revealing that they’ve both had sex on an airplane.

As the questions became raunchier, Kim asked Hailey: “What turns you on the most?”

Hailey answered: “I think kissing. I like the make-out.”

Kim agreed, adding: “I love a make-out.”

“What was your worst date ever?” Hailey asked Kim.

Taking a shot of tequila, Kim replied: “Should I drink on that one? I’m just going to drink on this one.”

“Have you ever joined the mile high club?” Kim then asked Hailey.

Hailey simply responded: “Yes.” Kim then added: “Samesies.”

“I was going to say, I don’t even need to ask you that,” Hailey then joked.
