Heidi Klum celebrated her 50th birthday with a lavish, star-studded bash in Los Angeles on Friday.

On the day after her birthday, the supermodel dazzled in an outfit ornate with diamonds as she rang in milestone at her extravagant 1920s-inspired, Gatsby-themed party.

The television host looked mesmerizing in a long, sheer dress with a white bra and miniskirt-style panels as well as a dripping rhinestone design.

The film producer — who enjoyed a lunch date with her husband, Tom Kaulitz, 33, on Wednesday — reposted many photos and videos from her fellow A-list guests to her Instagram Story.

Some of the stars celebrating the blonde bombshell’s birthday included her America’s Got Talent costars, Sofia Vergara and Howie Mandel, and supermodel Alessandra Ambrosio.

In the snaps and clips, Klum looked radiant in various angles showing off the sheer, open back garment featuring diamonds decorating the high neckline, long sleeves, and floor-sweeping skirt.

For the special occasion, the former Victoria’s Secret Angel modeled a rhinestone bandana headpiece over her platinum blonde hair in loose waves that were parted down the middle.

The businesswoman sported a cropped and fluffy white fur jacket over the sexy and sparkling flapper-inspired dress.

She added an additional touch of glamour by rocking a sultry smokey eyeshadow look highlighted by a generous amount of light-reflecting, silver glitter.

She wore an otherwise minimal makeup look featuring light pink blush and a perfect nude lip. 

Ambrosio also snapped a moment where Klum shared a quick smooch with her musician husband before being presented with her birthday cake.

Kaulitz was seen wearing a stylish black velvet blazer over a white button-down and trousers.

During the party, Vergara also documented and snapped a photo of the stunning cake with five tiers of bronze designs and white roses.
