Stephanie Seymour was one of THE supermodels of the 1990's, and truth be told, she is an absolutely stunning 45-year old mother of four. But her latest spread for Harper's Bazaar with two of her sons has many raising their eyebrows.

The photo spread has her in lingerie while in sexy poses with her two sons, 20-year-old Peter and 17-year-old Harry.

Three of the photos stand out: one showing her in a backless dress facing one son whose arm is wrapped around her waist, while the other son's hand is near her rear end.

Another in which she's wearing a corset and lace-up boots while her sons pull at the boot strings; and a third in which she's dressed in a sheer dress and her sons are kneeling on either side of her body, with one hugging her thigh and the other resting his head near her hip.

Three years ago, paparazzi photos showing Peter and his mother hugging and kissing at the beach in their bathing suits had people questioning what was going on.

Peter admitted on his Facebook page back then that he has a very open relationship with his mother that may be extra close due to the fact that he is gay.
