Hailey Bieber has shared a glimpse into her pre-birthday celebrations.

Ahead of her 27th birthday on November 22, the model posted a collection of photos showing fans a sliver of her exclusive weekend of festivities in Napa Valley, California.

We (her 50.7 million Instagram followers) saw her cuddling up to her husband, Justin Bieber, posing with The Kardashians star and model Kendall Jenner and serving numerous looks.

A collection of photos posted by TMZ showed the group of friends posing, laughing, and drinking wine.

But, the standout look? Bieber in an archival Thierry Mugler gown.

The red and strapless velvet body-con dress debuted in the late designer’s Fall 1998 couture collection, according to British Vogue, and features a scalloped neckline evocative of devil horns.

Paired with gold hoop earrings, matching gold watch and painted deep, wine-red nails.

“Starting the bday week off early,” she captioned a five-photo gallery of her in the gown.

“The best 48 hours (plus a blushing and smiling emoji, two red wine glass emojis and the emoji of two hearts forming a hand),” the second collection of photos on Instagram said.

But that’s not all. We can’t overlook the striped orange high-high boots.

Bieber paired the show-stopping boots with an oversized, beige cable-knit sweater and circular sunnies.

Earlier this week, she promoted a birthday product launch from her beauty brand Rhode. The limited edition Peptide Lip Tint will be released on November 22.

It has a baby pink tint, featuring a jelly-bean scent.
