She began her successful modeling career at the age of 18.

And on Saturday, Heidi Klum slipped on bright yellow trousers and a duster coat with a striped bikini top at the HQ2 Beachclub Opening in Atlantic City, New Jersey.

The 45-year-old supermodel was joined by fellow model Shanina Shaik, who rocked a black bikini top with a sheer cropped cover up and jeans.

Heidi sported a striped bikini top featuring yellow, white and pink tones; she paired the sports bra-style top with loose fitting neon bottoms.

The stunning mother of four chose a matching short sleeved cover up that grazed her calves.

She added strappy heels with layers of bracelets, adding delicate earrings; she sported red tinted sunglasses.

Heidi left her long tresses loose with a center part, opting for minimal makeup.
