Heidi Klum rocked the Victoria’s Secret ‘Very Sexy’ Fantasy Bra in 2003 while 4 months’ pregnant

Heidi Klum was four months’ pregnant under those (nearly) flat abs when she flaunted her angelic bod at the Victoria’s Secret Fashion Show in 2003.

You wouldn’t know it from the photo she posted to commemorate her oldest child Leni’s 17th birthday, but the caption said it all.

“Happy 17th birthday LENI,” wrote Klum, 47, on Instagram alongside a video clip of her on the runway. “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.”

The throwback video showed Klum clad in Victoria’s Secret “Very Sexy” Fantasy Bra. A subtle baby bump is discernible at second glance, making this perhaps the very earliest photo available of Klum’s firstborn.

Klum gave birth to Leni in 2004 soon after her split from Italian businessman Flavio Briatore, and while she was dating singer Seal, who adopted the girl after he and Klum married. The pair would have three more children before divorcing in 2014.

That first daughter, though, has now herself grown up to be a model, following in her famous mother’s footsteps, opening Berlin Fashion Week with a walk down the virtual runway earlier this year – to Klum’s unending pride, as she told People in February.

“I loved you before you were born, and I will love you long after I close my eyes forever,” the doting mama wrote in her Instagram post.
