HEIDI KLUM: CITY MAGAZINE SEXY

She may no longer work the runway, but Heidi Klum is still a cover girl.

The 37-year-old German-born beauty was all smiles as she celebrated her cover of the September issue of CITY magazine at The Lambs Club in New York City today (September 8 ).

Meanwhile, in her undying attempt to brand everything, Heidi has teamed up with sports firm New Balance to launch her own range of activewear.

“I definitely know what it means to be on the go: four kids, school drop-offs, playdates, sports activities, the park, it goes on and on,” she says. “As much as I love the gowns and sparkly clothes, what I turn to most in my closet are active clothes that look stylish but are comfortable and work for all of my activities. That is exactly what my line for New Balance is all about.”

The advertising campaign was shot by Rankin with the help of Amazon’s clothing creative director Jan Dikkers.

The collection, which features tunics, woven tops, leggings and outerwear, will be available from October 7.

Earlier this year, Heidi also released two maternity ranges as she wanted expectant mothers to still be stylish.
