Navel gazing: Karolina Kurkova in Miami over the weekend
Victoria's Secret model Karolina Kurkova put her bombshell curves on show during a photo shoot in Miami over the weekend, but it was her peculiar belly button that was attracting all the attention.
The Czech blonde's unusual navel had onlookers perplexed as she frolicked on the beach over the weekend in a tiny white bikini.
It's not the first time her almost non-existent belly button has drawn attention.
A source has revealed magazine and catalogue art directors routinely airbrush one in for in post-production.
'Karolina’s body is amazing, but her belly button is unusual,' a fashion insider told Page Six magazine.
'It disappears in photos, so we keep a collection of belly button shots in different positions, and Photoshop them on to her whenever she’s doing a bikini picture.'
Still, if she was at all self-conscious, she didn't let it show as she posed up on the foreshore.
The following day she was once again strutting her stuff at the lingerie company's catwalk extravaganza.

She was among the 35 Victoria's Secret models to hit the runway, including Heidi Klum and Orlando Bloom's current flame, Australian Miranda Kerr.
R&B singer Usher opened the show at the Fontainebleau Miami Beach hotel where the front row was filled with stars including Paris Hilton, John Stamos, Kim Kardashian, Martha Stewart and Klum's husband, Seal.
Karolina, who has appeared in campaigns for Yves Saint Laurent, Ralph Lauren, Oscar de la Renta, Chanel and Balenciaga, remains one of the most in-demand models.

While her popularity shows no sign of slowing down, she hopes to cross over into acting.
She recently filmed a small part in Sienna Miller's upcoming action move G.I. Joe, which is scheduled for release next year.
