The second-generation celeb – who is the daughter of Stephen Baldwin – put her long, lean figure on full display in the sheer-as-can-be frock.

Dressing to match, she slipped into a pair of lilac heels and carried a deep plum clutch.

Hailey traded her blonde tresses for something more serious, seen with chocolate locks twisted into a chic up-do.

Mrs. Bieber skipped the red carpet and went straight inside for the event, where husband Justin was set to perform his hit Stay with Kid Laroi.

In addition to being there for Justin, she had the honor of introducing Kacey Musgraves’ performance.

But after her time on stage, Hailey was ready to relax, so she changed into a white tank top and feather-embellished pants to root for her love, who took the stage in a boxy blazer, jeans, and a  hoodie to accept the award for Best Pop Song for Peaches.

He would later be honored with Artist Of The Year.

The odds were in Bieber’s favor from the beginning.

The Canadian crooner came into the evening as the most-nominated artist, boasting seven whole nods, outranking Megan Thee Stallion, Billie Eilish, BTS, Doja Cat, Drake, Giveon, Lil Nas X and first-time nominee Olivia Rodrigo.
