Hailey Bieber nails the boss lady look!

On Wednesday, October 23, the 27-year-old model had the support of her husband Justin Bieber as the couple attended a Rhode party in Los Angeles. This was their first public appearance since announcing they welcomed their son Jack Blues in August.

The new parents were pictured at Funke in Beverly Hills celebrating the launch of Hailey's skincare line's new Barrier Butter, available October 28th.

Hailey dressed to impress for the outing, wearing an oversized gray blazer from Saint Laurent by Anthony Vaccarello, which she paired with matching pleated trousers and a striped shirt.

The beauty mogul completed the look with a maroon patterned tie, a chic up-do and black glasses. She carried a maroon Saint Laurent clutch and added height with pointed heels.

Justin, 30, on the other hand, opted for a more casual look, wearing a brown checked jacket and jeans, which he teamed with sunglasses and a brown hat.

Hailey made sure to document her outfit on her Instagram Stories, giving fans a closer look as she zoomed in on her outfit and makeup while taking a selfie. She also gave fans a glimpse of the outfit as she posed in front of a mirror in another clip.

Although Wednesday was Hailey's first event since giving birth, on Saturday, October 19, she stepped out with her friend Lori Harvey to attend Don Toliver's concert in Los Angeles, where Justin made a surprise appearance on stage.

The pair sang their song “Private Landing” from Toliver’s 2023 studio album Lovesick at Crypto.com Arena. The hit track also features Future.

The evening came nearly two months after the Biebers announced the arrival of their first child on August 24.

“WELCOME HOME JACK BLUES BIEBER,” Justin wrote on Instagram at the time, alongside a photo of the newborn's tiny foot.
