Heidi Klum’s rarely seen 15-year-old daughter Lou joined her on a luxury shopping spree in New York City this week.

She is the youngest of Klum’s three children with singer ex-husband Seal, 62, who she divorced in 2014 after nearly a decade of marriage.

Lou towered over the 5foot9inch German supermodel, 51, as they exited the Balenciaga flagship store with Klum’s mother Erna, 80, on Wednesday.

Klum carried a large Balenciaga shopping bag while Lou seemingly left empty handed. 

For their NYC outing, Klum looked stylish in a gray and black tweed overcoat over matching gray slacks and black shoes.

Meanwhile, Lou — who will celebrate her 16th birthday in October — kept it casual in a red basketball jersey layered over a black sweatshirt and baggy black pants.

Later in the day, Heidi, Lou and Erna headed to lunch at Cipriani in Downtown Manhattan, where they met up with Heidi’s eldest daughter and model, Leni, 20.

Along with Leni and Lou, Heidi is also mom to sons Henry, 19, and Johan, 18.

She shares Lou and her two boys with ex-husband Seal while Leni was conceived during her brief romance with Italian businessman Flavio Briatore.

While still married to Heidi in 2009, Seal decided to adopt Leni.

While the four kids have mostly been raised out the spotlight, Lou, Leni, Henry and Johan have increasingly entered the public eye over the past few years.

This includes joining their superstar dad at premieres and features on their mom’s social media.

Lou has appeared on her mother’s Instagram in a number of sweet snaps, taken on various trips and events, like Coachella.

Last month, Klum revealed that Lou does debate tournaments on the weekend, loves arts and crafts, and is a part of the choir at her school.

‘I think is going to be the president, so watch out,’ the mother-of-four told Access Hollywood. ‘She has interest in everything.’

Klum’s mother Erna, 80, also tagged along as they shopped at the Balenciaga flagship store 

Still, Klum teased that Lou is interested in following her footsteps down the runway.

She’s like, ‘Okay, when can I do this modeling stuff?’ and I’m like, ‘You just turned 15. Let’s wait a H๏τ minute, you know?”

Lou’s older sister Leni, who has more than 1.8 million Instagram followers, marked her modeling debut by gracing the cover of Vogue Germany, alongside her mom.

Meanwhile, Klum’s son Henry Samuel made his runway debut at Paris Fashion Week back in January at age 19.

18-year-old Johan, who is in college, has also expressed interest in modeling.

Lou, the youngest of the four kids, was born on October 9, 2009 in Los Angeles, California.

At the time, Seal wrote in a statement, ‘It’s difficult to imagine loving another child as much as you love your existing children. Anyone who has a family will tell you this. Where will one find that extra love? If you love your existing children with all of your heart, how then can one possibly find more heart with which to love another?’

‘The answer to this question came in the form of our fourth child and second daughter. Lou Sulola Samuel was born, and from the moment she looked into both of our eyes, it was endless love at first sight,’ he continued.

Klum previously gushed back in 2021 that Lou is her only child that shares her love for Halloween.

‘I was hoping that I would pᴀss this on even to my kids, but out of four, there’s only one that really is going for it and that’s Lou,’ she told People.

Lou also inspired Klum to promote body positivity on her new platform, Modelverse, last year.

After years of watching her daughter play Roblox, Klum recalls asking Lou what was missing in the game and the two figured out that only one certain kind of body type was available as an avatar to use.

This led Klum to want to change that on her platform Modelverse, a virtual experience for Roblox, where players can walk the catwalk in major fashion shows as their avatar.

‘For most younger kids, I don’t think the diversity idea, or the importance of it, has even sunken into [their heads].

‘They don’t even realize,’ Klum said.

‘The world is not looking like this, and most of us are not looking like this.’

And the avatar shapes are important to her.

‘I wanted people to either come with their own avatar or create a new avatar [and have it be] however they want, and not just that one typical kind of body shape, which I think is so out of date,’ she explained in an interview with People.

‘We’re in 2024. I think diversity is bigger than ever these days, so why is this not reflected in any of the games,’ Klum added.

‘I feel like there needs to be a variety in avatars, so I wanted to make a world where there’s diversity in body shapes.’
