Heidi Klum looks unrecognizable in cut-out swimsuit in sultry throwback snaps

The supermodel treated her husband Tom Kaulitz to a bikini photo that oozed siren-core on Valentine's Day this year. The black-and-white photo was shot by photographer Rankin and depicted the blonde bombshell showing off her toned physique in a swimming pool. Heidi wore a triangle bikini top and matching thong bottoms while her hair was styled into beach waves.

Heidi looked sensational in a red string bikini during her family holiday to Aspen in December last year. The America's Got Talent judge braved the snow in a hot tub as she donned a miniature scarlet bikini accessorized with chunky gold jewelry. The fiery number matched the model's stunning red manicure, while she held a glass of chilled wine. 

The star opted for a fluffy green bucket hard paired with daring oversized blue sunglasses. 

The mother-of-three enjoyed a romantic vacation with her husband and was sure to post a few jaw-dropping swimwear snaps. Heidi was pictured floating in the sea in a pink-and-blue floral bikini set.

Heidi shared a throwback photograph of her application to a modeling competition in 1992. The budding star donned a black swimsuit adorned with blue, orange, and yellow abstract prints.

The supermodel doesn't shy away from a bold leopard print ensemble when it comes to packing for her tropical vacations. Heidi exuded chic in a leopard print bikini and straw sunhat while posing for a photograph on the rocks next to the sea.
