Heidi Klum embraces her German roots in traditional dress as she joins rockstar husband and family at HeidiFest in Munich

Heidi Klum celebrated HeidiFest in her German homeland with her family right by her side.

The 53-year-old model donned traditional Bavarian attire as she arrived at the event in Munich with her younger husband Tom Kaulitz, 37, daughter Leni, 22, son Henry Samuel, 21, and mother Erna Klum.

She looked stunning in a vibrant, low-cut yellow floral dirndl - a traditional dress that features a lace-up bodice and wide apron skirt. Klum styled the look with a matching flower wreath and yellow heels. 

Her husband also opted for a traditional look, wearing distressed olive-brown lederhosen with a light blue shirt and vest over it. The Tokio Hotel guitarist completed the look with knee-high grey wool socks.

The pair, who married in 2019, were seen sharing a passionate smooch at the event.  

HeidiFest - which kicks off the traditional annual Oktoberfest celebrations - is a star-studded party held at the iconic Hofbrauhaus beer hall.

Klum's mom Erna opted for a vivid red dress with a matching wreath and boots. 

Her son Henry matched Kaulitz in a similar traditional look but opted to keep his socks rolled down.

Meanwhile Leni wowed in a baby blue dress paired with a blue apron and UGG slippers.

The Victoria's Secret Angel shares Leni with Italian businessman Flavio Briatore, and Henry with ex-husband Seal. She also has son Johan, 19, and daughter Lou, 16, with Seal. The British musician officially adopted Leni in 2009.

Klum and Seal were married from 2005 until 2014.

The festival comes shortly after the family celebrated Henry's 21st birthday on September 12.

Klum surprised her son with a flashy, red Ferrari F430 to mark the occasion.

She shared an Instagram video of the moment she presented the special gift to him and captured his surprised reaction.

Henry also posed with his grandmother 

In the clip, Klum was standing outside alongside the car, which costs upwards of six figures and averages around $200,000.

Kaulitz led Henry outside toward the surprise awaiting him.

'I can't believe it is that time. You've been waiting for so many years,' Klum said to Henry in the video.

'Oh my God! Jesus Christ. I don't even know what to say,' Henry could be heard saying after the luxury car was revealed to him.

Kaulitz was also heard in the birthday surprise video, explaining that he held up his end of the bargain after he and Henry made a video game bet many years earlier.

He said he purchased the Ferrari at a car show 'last year' and had been hiding the big purchase in their garage 'the whole time' leading up to Henry's birthday.

Klum noted how her husband 'kept his promise' to Henry. 'Literally, it's what? Seven years ago when you guys said that?'

Klum then shared a follow-up post and revealed the gift was related to when Henry was a teenager and made a bet with his stepfather Kaulitz.

'It's happening on Christmas, and if I lose Mario Kart, then I can't play video games for three months, and I have to do a painting of me driving,' Henry said in the clip. 'But if I win, then Tom has to give me a Ferrari when I'm 21.'

On the same day, Klum also shared an adorable throwback photo of her four children when they were young children.

In the black-and-white snapshot, her children were wearing birthday hats and smiling at each other during a special moment.

Klum wrote in her caption alongside the adorable picture of her kids and a slew of red heart emojis: 'Henry WOW. Time flies. We love you sooooooo much. Happy 21 Birthday.'
