At the fancy event where they were showing the French movie "La Passion De Dodin Bouffant," something interesting happened on the red carpet. Heidi Klum, the famous 49-year-old German model, looked super classy as she walked into the spotlight.

Heidi Klum owned the red carpet at the Cannes Film Festival! She rocked a bold yellow dress with cool cut-outs that got everyone's attention.

But here's the unexpected part: She had a major wardrobe malfunction that seemed to show a bit more than she intended, including what looked like her nipple.

It happened while the 49-year-old German model was gracefully strutting the red carpet right before they screened the French movie "La Passion De Dodin Bouffant."

Heidi Klum looked stunning as she walked down the red carpet in the gorgeous yellow dress by Zuhair Murad Couture.

The dress had a flowing cloak that followed behind her, and there were daring diamond-shaped cut-outs on her chest that added a touch of edge.

Everyone couldn't take their eyes off her. The flowing cloak and the thigh-high leg split in her dress made her outfit even more eye-catching.

To complete the jaw-dropping look, she wore bejeweled beads on the shoulders of her flowing cape. It was truly a show-stopping ensemble.

To add some extra glam to her outfit, she wore big diamond rings and rocked clear heels. And her famous blonde hair flowed gracefully over her shoulder, completing her iconic look.

In the middle of all the fancy glamour, something unexpected went down and Heidi Klum had a wardrobe malfunction.

It happened during a photo session when Heidi was goofing around and threw the fabric of her dress in the air.

But oops, her nipple accidentally got exposed and it caught everyone by surprise.

Heidi Klum didn't let the fashion mishap bother her at all, showing off her cool attitude. She kept on posing and smiling like a pro during the whole event.

Before the Cannes event, Heidi shared a bunch of pictures on social media, giving her followers a sneak peek of the bold dress she was rocking.

She even treated them to a close-up shot of the revealing and busty outfit. She knows how to keep things exciting!

She added a yellow heart emoji as the caption and simply wrote: "CANNES."

Heidi, a proud mom of four, is famous for proudly showing off her amazing body. In the past, she's been open about not hesitating to strip down.

She even mentioned in an interview with Access last year: "I feel the same as I always did. You don't have to ask me twice to take my clothes off and show myself in lingerie."

"It's kind of like putting on an old hat, in a way."

Just a few days ago, the supermodel had an Instagram Q&A session with her fans, where she gave them a peek into her personal thoughts and experiences.

In the Q&A session, Heidi shared some fun facts about her curves, all while rocking a cozy look with a fur hat and a gray wool cardigan.

She encouraged her followers to ask her anything, and one fan took the opportunity to inquire about her bra size. And guess what? Heidi happily obliged.

With a playful emoji grin and a clip art image of a red lace bra, she replied: "36C."

As Heidi celebrates her 50th birthday, she's expected to attend numerous glamorous events this week.

But even as she reaches this important milestone, Klum has made it clear that she won't let the number define or alter her journey.

"For me, just a number, you know? Because I don't feel 50, internally," she shared with Entertainment Tonight.

"I mean, sometimes I look in the mirror and I'm like, 'Oh yeah, I am 50.' But internally, I feel like I'm 25."
