Heidi Klum reveals she was pregnant during 2003 Victoria’s Secret Fashion show

Heidi Klum paid tribute to her eldest child, daughter Leni, on Tuesday as the aspiring model turned 17.

In an Instagram post, the German-born supermodel, who shares Leni with ex-husband Seal, shared a clip of herself strutting her stuff on the Victoria’s Secret catwalk in 2003. 

In her birthday message, the America’s Got Talent judge revealed she was pregnant at the time – despite displaying a very flat tummy in her lingerie.

‘Happy 17th birthday LENI, I am not alone walking down that catwalk here. If I look close enough then I can see you bumping right along at 4 months @LeniKlum.’ Klum, 47, wrote.

‘I loved you before you were born, and I will love you long after I close my eyes forever. ❤️❤️❤️’ the devoted mom added.

Last month Leni landed her first-ever solo magazine cover. 

The teen has followed in her supermodel mom’s footsteps by gracing Glamour Germany’s 20th anniversary issue, two decades after Heidi became the magazine’s first cover model.

Alongside the cover, which sees her rock a bold floral gown, Heidi’s lookalike daughter wrote on Instagram: ‘Thank you to everyone who made my first solo cover so special. It’s an honor to share this with my mama @heidiklum who was Glamour Germany’s first ever cover model. (sic)’

She also captioned a clip of her mother’s cover which morphs into her own: ‘2001 [fast forward emoji] 2021.’

Proud mom Heidi posted her daughter’s cover on her own page on the social media app and gushed: ‘Couldn’t be more proud of you @leniklum.’

Leni launched her modelling career last year, with a joint cover with her mom for Vogue Germany’s January/February 2021 issue. 

The German catwalk beauty’s teenage girl – whose biological father is Flavio Briatore – starred alongside her mom on the cover of the prestigious fashion magazine, with the pair rocking matching colorful trouser suits. 

Leni, whose mother had earlier teased that her daughter was keen to follow in her footsteps with a career in modelling, revealed in the cover interview that she had first received offers to model when she was just 12 or 13. 

However, Heidi – who also has Lou, 11, plus sons Henry, 15, and Johan, 14, with ex-husband Seal – wouldn’t allow her to do it so young and in hindsight she understood why.

Leni told the publication: ‘It was only a matter of time before I would try it myself as a model. The first offer came when I was only 12 or 13, from a brand I loved to wear: Brandy Melville. 

‘Back then I begged Mom, but no chance! I now understand that it would have been too early. 

‘For most other jobs, I’d have to stifle my crazy ways to look ‘professional.’ As a model, I can let everything out and just be who I am. The job is the perfect outlet for all the energy that I have in me.’
