Heidi Klum busts a move in bra top and itty-bitty feathery shorts

Heidi Klum rocked a short and sexy ‘fit to support her husband, Tom Kaulitz, and brother-in-law, Bill Kaulitz, as their band played at Berlin’s Pride celebration on Saturday — and her feathered ensemble looked perfect to dance the night away.

The supermodel, 50, showed off some seriously tiny feather-trimmed shorts by Area ($595) and a lacy white bustier top on Instagram as she got ready for Tokio Hotel’s performance at the city’s pride event, known as Christopher Street Day Berlin or CSD.

“Let’s Party BERLIN  #CSD #csdberlin,” she captioned her post, which included three photos and a fun video as she rocked out before the show.

In the first pic, the former Victoria’s Secret Angel gives a look at the back of her denim cutoffs, turning her back to the camera and whipping her blond locks in the air.

Klum — who never shies away from a sexy look — sports a pair of six-inch nude Christian Louboutin platform heels ($1,095) with her shorts, adding a Western-style brown leather belt and fishnet tights to her look.

She leans forward and puckers up while revealing some major cleavage in a second snap, pairing her white bustier with a gemstone pendant necklace and glittery blue eyeshadow.

The “America’s Got Talent” judge — who secretly married the 33-year-old Tokio Hotel guitarist in 2019 — shimmies and tosses her hair at the camera as she does a sexy dance to one of the band’s songs, with her multiple bangle bracelets jingling while she parties in what appears to be a Berlin hotel room.

She also posted footage from Tokio Hotel’s performance, going live on Instagram and then sharing a series of photos and videos from the CSD show as she covered up her outfit with a black bomber jacket.

In a rare move, Klum turned the comments on for her Tokio Hotel post, with many fans weighing in on the celebratory night.

“Tokio hotel and Heidi always ICONIC ” one Instagram user wrote.

Another added, “Best Band forever und Bills Outfit ist ” referring (in partial German) to Klum’s brother-in-law’s wild black-and-pink chaps ensemble for the show.

“I love that Heidi is expressing her support for Bill and being actively involved in his projects,” a third fan wrote.

After this fun outfit, we’re hoping Tokio Hotel hits the road again soon.
