Heidi Klum poses topless for campaign of her derriere collection

Heidi Klum knows exactly how to make business boom for her line of lingerie.

On Tuesday, the 42-year-old promoted Heidi Klum Intimates with a very sexy Instagram snap of herself half nude, save for a personalized black lace thong.

‘Love being cheeky in my @heidiklumintimates,’ she captioned the seductive image.

In the image, Heidi pressed her hands against a wall while flashing a coquettish over-the-shoulder expression.

Heidi’s blonde hair had a wet effect and was slicked over her head to unveil her radiant and shimmering complexion.

Adding an extra pop of sex appeal were her long black nails.
